Cassetteboy is the stage name of Mark Bolton and Steve Warlin (an author from Brixton). It was only upon the confirmation of their third album's release date in 2008 that they came forward and made their identities known. Their initial appearance was on the Di and Dodi Do Die 7" Record released in 2000 on the record label Barry's Bootlegs which is somehow related to the electronic music label Spymania. As well as producing two albums of their own, they have appeared on an album with DJ Rubbish entitled Inside A Whale's Cock Vol 1, which includes humorous cover versions of songs by Alanis Morissette and Jennifer Lopez (a skiffle cover of Jenny from the block), along with a parodical take on a song by The Streets. Their musical approach can be traced from the origins of sampling, musique concrète and the modern approach sometimes called Plunderphonics. Most pieces are painstakingly constructed from thousands of audio snippets taken from TV, radio, film and popular music; The Parker Tapes was constructed using the laborious, primitive process of manually splicing segments of audio together via a two-deck tape system, or "ghettoblaster"; later albums are constructed digitally using sound editing software.
