Phonograph record
–
The groove usually starts near the periphery and ends near the center of the disc. The phonograph disc record was the medium used for music reproduction until late in the 20th century. It had co-existed with the cylinder from the late 1880s. Records retained the largest market share even when new formats such as compact cassette were mass-marketed, by the late 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the vinyl record left the mainstream in 1991. The phonograph record has made a resurgence in the early 21st century –9.2 million records were sold in the U. S. in 2014. Likewise, in the UK sales have increased five-fold from 2009 to 2014, as of 2017,48 record pressing facilities remain worldwide,18 in the United States and 30 in other countries. The increased popularity of vinyl has led to the investment in new, only two producers of lacquers remains, Apollo Masters in California, USA, and MDC in Japan. Vinyl records may be scratched or warped if stored incorrectly but if they are not exposed to heat or broken. The large cover are valued by collectors and artists for the space given for visual expression, in the 2000s, these tracings were first scanned by audio engineers and digitally converted into audible sound. Phonautograms of singing and speech made by Scott in 1860 were played back as sound for the first time in 2008, along with a tuning fork tone and unintelligible snippets recorded as early as 1857, these are the earliest known recordings of sound. In 1877, Thomas Edison invented the phonograph, unlike the phonautograph, it was capable of both recording and reproducing sound. Despite the similarity of name, there is no evidence that Edisons phonograph was based on Scotts phonautograph. Edison first tried recording sound on a paper tape, with the idea of creating a telephone repeater analogous to the telegraph repeater he had been working on. The tinfoil was wrapped around a metal cylinder and a sound-vibrated stylus indented the tinfoil while the cylinder was rotated. The recording could be played back immediately, Edison also invented variations of the phonograph that used tape and disc formats. A decade later, Edison developed a greatly improved phonograph that used a wax cylinder instead of a foil sheet. This proved to be both a better-sounding and far more useful and durable device, the wax phonograph cylinder created the recorded sound market at the end of the 1880s and dominated it through the early years of the 20th century. Berliners earliest discs, first marketed in 1889, but only in Europe, were 12.5 cm in diameter, both the records and the machine were adequate only for use as a toy or curiosity, due to the limited sound quality

Compact disc
–
Compact disc is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was developed to store and play only sound recordings but was later adapted for storage of data. The first commercially available Audio CD player, the Sony CDP-101, was released October 1982 in Japan, standard CDs have a diameter of 120 millimetres and can hold up to about 80 minutes of uncompressed audio or about 700 MiB of data. The Mini CD has various diameters ranging from 60 to 80 millimetres, they are used for CD singles, storing up to 24 minutes of audio. At the time of the introduction in 1982, a CD could store much more data than a personal computer hard drive. By 2010, hard drives commonly offered as much space as a thousand CDs. In 2004, worldwide sales of audio CDs, CD-ROMs and CD-Rs reached about 30 billion discs, by 2007,200 billion CDs had been sold worldwide. In 2014, revenues from digital music services matched those from physical format sales for the first time. American inventor James T. Russell has been credited with inventing the first system to record information on an optical transparent foil that is lit from behind by a high-power halogen lamp. Russells patent application was first filed in 1966, and he was granted a patent in 1970, following litigation, Sony and Philips licensed Russells patents in the 1980s. The compact disc is an evolution of LaserDisc technology, where a laser beam is used that enables the high information density required for high-quality digital audio signals. Prototypes were developed by Philips and Sony independently in the late 1970s, although originally dismissed by Philips Research management as a trivial pursuit, the CD became the primary focus for Philips as the LaserDisc format struggled. In 1979, Sony and Philips set up a joint task force of engineers to design a new audio disc. After a year of experimentation and discussion, the Red Book CD-DA standard was published in 1980, after their commercial release in 1982, compact discs and their players were extremely popular. Despite costing up to $1,000, over 400,000 CD players were sold in the United States between 1983 and 1984, by 1988 CD sales in the United States surpassed those of vinyl LPs, and by 1992 CD sales surpassed those of prerecorded music cassette tapes. The success of the disc has been credited to the cooperation between Philips and Sony, who came together to agree upon and develop compatible hardware. The unified design of the disc allowed consumers to purchase any disc or player from any company. In 1974, L. However, due to the performance of the analog format

London
–
London /ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain and it was founded by the Romans, who named it Londinium. Londons ancient core, the City of London, largely retains its 1. 12-square-mile medieval boundaries. London is a global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism. It is crowned as the worlds largest financial centre and has the fifth- or sixth-largest metropolitan area GDP in the world, London is a world cultural capital. It is the worlds most-visited city as measured by international arrivals and has the worlds largest city airport system measured by passenger traffic, London is the worlds leading investment destination, hosting more international retailers and ultra high-net-worth individuals than any other city. Londons universities form the largest concentration of education institutes in Europe. In 2012, London became the first city to have hosted the modern Summer Olympic Games three times, London has a diverse range of people and cultures, and more than 300 languages are spoken in the region. Its estimated mid-2015 municipal population was 8,673,713, the largest of any city in the European Union, Londons urban area is the second most populous in the EU, after Paris, with 9,787,426 inhabitants at the 2011 census. The citys metropolitan area is the most populous in the EU with 13,879,757 inhabitants, the city-region therefore has a similar land area and population to that of the New York metropolitan area. London was the worlds most populous city from around 1831 to 1925, Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Pauls Cathedral, Tower Bridge, Trafalgar Square, and The Shard. The London Underground is the oldest underground railway network in the world, the etymology of London is uncertain. It is an ancient name, found in sources from the 2nd century and it is recorded c.121 as Londinium, which points to Romano-British origin, and hand-written Roman tablets recovered in the city originating from AD 65/70-80 include the word Londinio. The earliest attempted explanation, now disregarded, is attributed to Geoffrey of Monmouth in Historia Regum Britanniae and this had it that the name originated from a supposed King Lud, who had allegedly taken over the city and named it Kaerlud. From 1898, it was accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos. The ultimate difficulty lies in reconciling the Latin form Londinium with the modern Welsh Llundain, which should demand a form *lōndinion, from earlier *loundiniom. The possibility cannot be ruled out that the Welsh name was borrowed back in from English at a later date, and thus cannot be used as a basis from which to reconstruct the original name. Until 1889, the name London officially applied only to the City of London, two recent discoveries indicate probable very early settlements near the Thames in the London area

Music video
–
A music video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to more than just a song. Tie ins and merchandising could be used in toys or marketing campaigns for food, although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by terms including illustrated song, filmed insert, promotional film, promotional clip, promotional video, song video. Music videos use a range of styles of contemporary videomaking techniques, including animation, live action filming, documentaries. Some music videos blend different styles, such as animation, music, combining these styles and techniques has become more popular because of the variation it presents to the audience. Many music videos interpret images and scenes from the songs lyrics, other music videos may be without a set concept, being merely a filmed version of the songs live performance. Product placement is a technique in music videos, exemplified by the appearance of the Beats Pill in numerous hip hop videos. In 1894, sheet music publishers Edward B, marks and Joe Stern hired electrician George Thomas and various performers to promote sales of their song The Little Lost Child. Using a magic lantern, Thomas projected a series of images on a screen simultaneous to live performances. This would become a form of entertainment known as the illustrated song. In 1926, with the arrival of many musical short films were produced. Vitaphone shorts featured many bands, vocalists and dancers, early 1930s cartoons featured popular musicians performing their hit songs on-camera in live-action segments during the cartoons. The early animated films by Walt Disney, such as the Silly Symphonies shorts and especially Fantasia, the Warner Brothers cartoons, even today billed as Looney Tunes and Merrie Melodies, were initially fashioned around specific songs from upcoming Warner Brothers musical films. Live action musical shorts, featuring such performers as Cab Calloway, were also distributed to theaters. Blues singer Bessie Smith appeared in a short film called St. Louis Blues featuring a dramatized performance of the hit song. Numerous other musicians appeared in short musical subjects during this period, soundies, produced and released from 1940 to 1947, were musical films that often included short dance sequences, similar to later music videos

VHS
–
The Video Home System is a standard for consumer-level analog video recording on tape cassettes. Developed by Victor Company of Japan in the early 1970s, it was released in Japan in late 1976, from the 1950s, magnetic tape video recording became a major contributor to the television industry, via the first commercialized video tape recorders. At that time, the devices were used only in professional environments such as television studios. In the 1970s, videotape entered home use, creating the video industry and changing the economics of the television. The television industry viewed videocassette recorders as having the power to disrupt their business, in the 1980s and 1990s, at the peak of VHSs popularity, there were videotape format wars in the home video industry. Two of the formats, VHS and Betamax, received the most media exposure, VHS eventually won the war, dominating 60 percent of the North American market by 1980 and emerging as the dominant home video format throughout the tape media period. Optical disc formats later began to better quality than analog consumer video tape such as standard. The earliest of these formats, LaserDisc, was not widely adopted, however, after the introduction of the DVD format in 1997, VHSs market share began to decline. By 2008, DVD had replaced VHS as the preferred method of distribution. After several attempts by other companies, the first commercially successful VTR, at a price of US$50,000 in 1956, and US$300 for a 90-minute reel of tape, it was intended only for the professional market. Kenjiro Takayanagi, a broadcasting pioneer then working for JVC as its vice president, saw the need for his company to produce VTRs for the Japan market. In 1959, JVC developed a video tape recorder. In 1964, JVC released the DV220, which would be the companys standard VTR until the mid-1970s, in 1969 JVC collaborated with Sony Corporation and Matsushita Electric in building a video recording standard for the Japanese consumer. The effort produced the U-matic format in 1971, which was the first format to become a unified standard, U-matic was successful in business and some broadcast applications, but due to cost and limited recording time very few of the machines were sold for home use. Soon after, Sony and Matsushita broke away from the collaboration effort, Sony started working on Betamax, while Matsushita started working on VX. JVC released the CR-6060 in 1975, based on the U-matic format, Sony and Matsushita also produced U-matic systems of their own. In 1971, JVC engineers Yuma Shiraishi and Shizuo Takano put together a team to develop a consumer-based VTR, by the end of 1971 they created an internal diagram titled VHS Development Matrix, which established twelve objectives for JVCs new VTR. These included, The system must be compatible with any television set

Record producer
–
A record producer or music producer oversees and manages the sound recording and production of a band or performers music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process, the roles of a producer vary. The producer may perform these roles himself, or help select the engineer, the producer may also pay session musicians and engineers and ensure that the entire project is completed within the record companies budget. A record producer or music producer has a broad role in overseeing and managing the recording. Producers also often take on an entrepreneurial role, with responsibility for the budget, schedules, contracts. In the 2010s, the industry has two kinds of producers with different roles, executive producer and music producer. Executive producers oversee project finances while music producers oversee the process of recording songs or albums. In most cases the producer is also a competent arranger, composer. The producer will also liaise with the engineer who concentrates on the technical aspects of recording. Noted producer Phil Ek described his role as the person who creatively guides or directs the process of making a record, indeed, in Bollywood music, the designation actually is music director. The music producers job is to create, shape, and mold a piece of music, at the beginning of record industry, producer role was technically limited to record, in one shot, artists performing live. The role of producers changed progressively over the 1950s and 1960s due to technological developments, the development of multitrack recording caused a major change in the recording process. Before multitracking, all the elements of a song had to be performed simultaneously, all of these singers and musicians had to be assembled in a large studio and the performance had to be recorded. As well, for a song that used 20 instruments, it was no longer necessary to get all the players in the studio at the same time. Examples include the rock sound effects of the 1960s, e. g. playing back the sound of recorded instruments backwards or clanging the tape to produce unique sound effects. These new instruments were electric or electronic, and thus they used instrument amplifiers, new technologies like multitracking changed the goal of recording, A producer could blend together multiple takes and edit together different sections to create the desired sound. For example, in jazz fusion Bandleader-composer Miles Davis album Bitches Brew, producers like Phil Spector and George Martin were soon creating recordings that were, in practical terms, almost impossible to realise in live performance. Producers became creative figures in the studio, other examples of such engineers includes Joe Meek, Teo Macero, Brian Wilson, and Biddu

Single (music)
–
In music, a single or record single is a type of release, typically a song recording of fewer tracks than an LP record, an album or an EP record. This can be released for sale to the public in a variety of different formats, in most cases, a single is a song that is released separately from an album, although it usually also appears on an album. Typically, these are the songs from albums that are released separately for promotional uses such as digital download or commercial radio airplay and are expected to be the most popular, in other cases a recording released as a single may not appear on an album. As digital downloading and audio streaming have become prevalent, it is often possible for every track on an album to also be available separately. Nevertheless, the concept of a single for an album has been retained as an identification of a heavily promoted or more popular song within an album collection. Despite being referred to as a single, singles can include up to as many as three tracks on them. The biggest digital music distributor, iTunes, accepts as many as three tracks less than ten minutes each as a single, as well as popular music player Spotify also following in this trend. Any more than three tracks on a release or longer than thirty minutes in total running time is either an Extended Play or if over six tracks long. The basic specifications of the single were made in the late 19th century. Gramophone discs were manufactured with a range of speeds and in several sizes. By about 1910, however, the 10-inch,78 rpm shellac disc had become the most commonly used format, the inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century.26 rpm. With these factors applied to the 10-inch format, songwriters and performers increasingly tailored their output to fit the new medium, the breakthrough came with Bob Dylans Like a Rolling Stone. Singles have been issued in various formats, including 7-inch, 10-inch, other, less common, formats include singles on digital compact cassette, DVD, and LD, as well as many non-standard sizes of vinyl disc. Some artist release singles on records, a more common in musical subcultures. The most common form of the single is the 45 or 7-inch. The names are derived from its speed,45 rpm. The 7-inch 45 rpm record was released 31 March 1949 by RCA Victor as a smaller, more durable, the first 45 rpm records were monaural, with recordings on both sides of the disc. As stereo recordings became popular in the 1960s, almost all 45 rpm records were produced in stereo by the early 1970s

Depeche Mode also rank number 98 on VH1s 100 Greatest Artists of All Time, Depeche Modes origins date to 1977, when schoolmates Vince Clarke and Andy Fletcher formed a Cure-influenced band called No Romance In China, with Clarke on vocals and guitar and Fletcher on bass. Fletcher would later recall, Why am I in the band and it was accidental right from the beginning. I was actually forced to be in the band, I played the guitar and I had a bass, it was a question of them roping me in. In 1979, Clarke played guitar in an Ultravox rip-off band, in 1978–79, Martin Gore played guitar in an acoustic duo, Norman and the Worms, with school friend Phil Burdett on vocals. In 1979, Marlow, Gore and friend Paul Redmond formed a band called the French Look, with Marlow on vocals/keyboards, Gore on guitar and Redmond on keyboards. In March 1980, Clarke, Gore and Fletcher formed a band called Composition of Sound, with Clarke on vocals/guitar, Gore on keyboards and Fletcher on bass. Soon after the formation of Composition of Sound, Clarke heard Wirral band Orchestral Manoeuvres in the Dark, along with OMD, other early influences included the Human League, Daniel Miller and Fad Gadget. Clarke and Fletcher switched to synthesisers, working odd jobs in order to buy or borrow the instruments from friends. Dave Gahan joined the band in 1980 after Clarke heard him perform at a scout hut jam session, singing a rendition of David Bowies Heroes. When explaining the choice for the new name taken from a French fashion magazine, Dépêche mode, Gore said, I like the sound of that

Dave and Sue were raised under the impression that their mothers second husband, in 1972, when Gahan was 10 years old, his stepfather died. Gahan recalled how he came one day and found this bloke at home. Of the incident, he has said, Ill never forget that day, when I came home from school, there was this stranger in my mums house. My mother introduced him to me as my real dad, I remember I said, that was impossible because my father was dead. How was I supposed to know who that man was, from that day on, Len often visited the house, until one year later he disappeared again. Since then he had no contact with us, by growing older, I thought about him more and more. The only thing my mother would say, was that he moved out to Jersey to open a hotel.

The album was entirely by Martin Gore and recorded after the departure of Vince Clarke. Alan Wilder was part of a tour in the United Kingdom occurring prior to the release of this album, but he had not officially joined the band yet. Melody Maker noted that A Broken Frame – as its name suggests – marks the end of a beautiful dream, reviewer Steve Sutherland considered that the songs of A Broken Frame sound like puerile infatuations papering over anonymity with weary words. He found that Shouldnt Have Done That is the only departure from their previous work. The cover artwork is a photograph, but is intended to resemble a painting and it depicts a woman cutting grain in an East Anglian field, near Duxford in Cambridgeshire. It was taken by Brian Griffin using a mixture of natural and artificial lighting, Griffin cited as inspirations Ukrainian and Russian art, especially the work of Kazimir Malevich, and German romantic art.

A-side and B-side
–
The terms A-side and B-side refer to the two sides of 78,45, and 33 1/3 rpm phonograph records, whether singles, extended plays, or long-playing records. Creedence Clearwater Revival had hits with both A-side and B-side releases, others took the opposite approach, producer Phil Spector was in the habit of filling B-sides with on-the-spot instrumentals that no one would confuse with the A-side. With this practice, Spector was assured that airplay was focused on the side he wanted to be the hit side, the earliest 10-inch,78 rpm, shellac records were single sided. Double-sided recordings, with one song on side, were introduced in Europe by Columbia Records. There were no record charts until the 1930s, and radio stations did not play recorded music until the 1950s, in this time, A-sides and B-sides existed, but neither side was considered more important, the side did not convey anything about the content of the record. The term single came into use with the advent of vinyl records in the early 1950s. At first, most record labels would randomly assign which song would be an A-side, under this random system, many artists had so-called double-sided hits, where both songs on a record made one of the national sales charts, or would be featured on jukeboxes in public places. As time wore on, however, the convention for assigning songs to sides of the record changed. By the early sixties, the song on the A-side was the song that the company wanted radio stations to play. It was not until 1968, for instance, that the production of albums on a unit basis finally surpassed that of singles in the United Kingdom. In the late 1960s stereo versions of pop and rock songs began to appear on 45s. The majority of the 45s were played on AM radio stations, by the early 1970s, double-sided hits had become rare. Album sales had increased, and B-sides had become the side of the record where non-album, non-radio-friendly, with the advent of cassette and compact disc singles in the late 1980s, the A-side/B-side differentiation became much less meaningful. With the decline of cassette singles in the 1990s, the A-side/B-side dichotomy became virtually extinct, as the dominant medium. However, the term B-side is still used to refer to the tracks or coupling tracks on a CD single. With the advent of downloading music via the Internet, sales of CD singles and other media have declined. B-side songs may be released on the record as a single to provide extra value for money. There are several types of material released in this way, including a different version, or, in a concept record
