Events and parties were often held in empty warehouses across the UK and were essentially illegal. Some of the most famous party promoters included Energy, Biology, Genesis'88, Sunrise, and Weekend World. Emerging from Danny Rampling's London club Shoom in late 1987, parties grew in northern cities like Manchester where warehouses had closed throughout the 1970s, and up to 10,000 people attended parties in smaller places such as Blackburn. Vague flyers around towns advertised events and information travelled by word of mouth between clubbers who were obliged to party incognito. For most promoters, keeping entry cheap was a political issue - many of the early parties cost just £1 to enter and prices rarely crept above £3. If police turned up to shut down a party, some would open the doors and let everyone in for free. Glaswegian DJ Tommy Smith encapsulated the scene's defiant spirit on Granada TV show 'Up Front', hosted by Tony Wilson, during a debate with disgruntled Blackburn residents and Conservative MPKen Hind. Smith declared that he was not on drugs or alcohol, simply “high on hope” and the phrase entered the clubbers' lexicon and was widely used to market club nights.
Music
The music was characterised by the "squelching" bass produced by the Roland TB-303 and loud repetitive beats. It originated in Chicago and took on new qualities when it came to Europe. Songs from the time period include "French Kiss" by Lil Louis "On & On" by Jesse Saunders, "Mystery of Love" by Fingers Inc., "Love Can't Turn Around" by Farley "Jackmaster" Funk & Jesse Saunders, "Back to Life " by Soul II Soul, "I've Lost Control" by Sleezy D, and "Your Only Friend" by Phuture. The catchphrase of partygoers was ‘Can you feel it?’, alluding to the Royal House cry from "Can you Party?".
Decline
The prevalence of drug use at these parties was in contrast to Thatcherism at the time, sparking moral panic. Police raided parties, such as a 10,000-strong rave in Nelson in 1990. In response, the Parliament of the United Kingdom passed the Entertainments Act of 1990 which brought the decline of acid house parties. As a result, the time period is often referred to as the Second Summer of Love. Eventually, acid house parties morphed into the rave scene.
