The Dark Side of the Moon is the eighth studio album by the English rock band Pink Floyd, released on 1 March 1973 by Harvest Records in the UK and Capitol Records in the US. Developed during live performances before recording began, it was conceived as a concept album that would focus on the pressures faced by the band during their arduous lifestyle, and also deal with the mental health problems of the former band member Syd Barrett, who departed the group in 1968. New material was recorded in two sessions in 1972 and 1973 at EMI Studios in London.

The album era was a period in popular music during the latter half of the 20th century in which the physical album was the dominant form of recorded music expression and consumption. Usually defined as lasting from the mid-1960s until the mid-2000s, it was driven primarily by three successive music recording formats: the 33⅓ rpm long-playing record (LP), the cassette tape, and the compact disc (CD). Rock musicians from the US and UK were often at the forefront of the era, which is sometimes called the album-rock era in reference to their sphere of influence and activity. The term "album era" is also used to refer to the marketing and aesthetic period surrounding a recording artist's album release.
