Dub is an electronic musical style that grew out of reggae in the late 1960s and early 1970s. It is commonly considered a subgenre of reggae, though it has developed to extend beyond that style. Generally, dub consists of remixes of existing recordings created by significantly manipulating the original, usually through the removal of vocal parts, emphasis of the rhythm section, the application of studio effects such as echo and reverb, and the occasional dubbing of vocal or instrumental snippets from the original version or other works.
Lee "Scratch" Perry was an early pioneer of the genre
A remix is a piece of media which has been altered or contorted from its original state by adding, removing, or changing pieces of the item. A song, piece of artwork, book, poem, or photograph can all be remixes. The only characteristic of a remix is that it appropriates and changes other materials to create something new.
