At one time it was feared and considered deeply subversive.
“Anti EP” is the third EP by British electronic music duo Autechre, released by Warp Records on 3 September 1994.
Anti EP was a protest against the Criminal Justice and Public Order Act 1994, which would prohibit raves (described as gatherings where music is played), with “music” being defined as a “succession of repetitive beats.”
Warning. ‘Lost’ and ‘Djarum’ contain repetitive beats. We advise you not to play these tracks if the Criminal Justice Bill becomes law. ‘Flutter’ has been programmed in such a way that no bars contain identical beats and can therefore be played under the proposed new law. However, we advise DJs to have a lawyer and a musicologist present at all times to confirm the non repetitive nature of the music in the event of police harassment.
