Shoom was a weekly all-nighter dance music event held at four nightclubs in London, between September 1987 and early 1990. It is widely credited with initiating the acid house movement in the UK. Show was founded by Danny Rampling, who was then an unknown DJ and record producer, and managed by his wife Jenni. It began at a 300-capacity basement gym on Southwark Street in South London. By May 1988, its growing popularity necessitated a move to the larger Raw venue on Tottenham Court Road, Central London, and a switch from Saturday to Thursday nights. Later relocations were to The Park Nightclub, Kensington and Busby's venue on Charing Cross Road. The early nights featured a mixture of Chicago house, Balearic and Detroit techno, mixed with contemporary pop and post-punk music. Its musical and visual culture evolved around the psychedelic drug LSD, and MDMA, an empathogen commonly known in the UK as ecstasy or E. Regular guest DJs included Carl Cox, Mark Moore and Andrew Weatherall.
