Rave Party Light Show

From the Acid House scene of the late 1980s, the scene transformed from predominantly a London-based phenomenon to a UK-wide underground youth movement. By 1991, organisations such as Fantazia, Universe, Raindance, and Amnesia House were holding massive legal raves in fields and warehouses around the country. One Fantazia party, called One Step Beyond, was an open-air, all-night affair that attracted 30,000 people. Other notable events included Vision at Pophams airfield in August 1992, with 40,000 in attendance and Universe's Tribal Gathering in 1993.
In the early 1990s, the scene was slowly changing, with local councils passing by-laws and increasing fees in an effort to prevent or discourage rave organisations from acquiring necessary licenses. This meant that the days of legal one-off parties were numbered. By the mid-90s, the scene had fragmented into many different styles of dance music, making large parties more expensive to set up and more difficult to promote. The happy old skool style was replaced by the darker jungle and the faster happy hardcore. Although many ravers left the scene due to the split, promoters such as ESP Dreamscape and Helter Skelter still enjoyed widespread popularity and capacity attendances with multi-arena events catering to the various genres. Particularly notable events of this period included ESP's Dreamscape 20 on 9 September 1995 at Brafield aerodrome fields, Northants and Helter Skelter's Energy 97 event on 9 Aug 1997 at Turweston Aerodrome, Northants.
The illegal free party scene also reached its zenith for that time after a particularly large festival, when many individual sound systems such as Bedlam, Circus Warp, DIY, and Spiral Tribe set up near Castlemorton Common. In May 1992, the government acted. Under the Criminal Justice and Public Order Act 1994, the definition of music played at a rave was given as:
"music" includes sounds wholly or predominantly characterised by the emission of a succession of repetitive beats.
