One of the elements of the U.K.'s 1994 Criminal Justice and Public Order Bill outlawed “gatherings around music characterized wholly or predominantly by the emission of a succession of repetitive beats.” This was seen at the time as a push against "rave" culture or "techno" music events. So far as I know, people in the U.K. still go to raves featuring EDM that falls within this definition umbrella. Was this law just not enforced? If it was, how did rave culture in the U.K. get around this law following this Act's passage in 1994?
Autechre released an EP in 1994 which included a protest of this bill by way of a track called Flutter in which no subsequent bar is repeated in the same way. They even state: "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.", which highlights just how ridiculous the bill was to enforce from a technical perspective.
