Acid hous is a sub-genre of house music that emphasizes a repetitive, hypnotic and trance-like style, often with samples or spoken lines rather than sung lyrics. Acid house's core electronic squelch sounds were developed by mid-1980s DJs from Chicago who experimented with the Roland TB-303 electronic synthesizer-sequencer. Acid house spread to the United Kingdom, Australia, and continental Europe, where it was played by DJs in the early rave scene. By the late 1980s, copycat tracks and acid house remixes brought the style into the mainstream, where it had some influence on pop and dance styles. Nicknamed "the sound of acid", acid house's influence on dance music is tangible considering the sheer number of electronic music tracks referencing acid house through the use of its sounds, including trance, Goa Trance, psytrance, breakbeat, big beat, techno, trip-hop and house music.

The first acid house records were produced in Chicago, Illinois. Phuture, a group founded by Nathan "DJ Pierre" Jones, Earl "Spanky" Smith Jr., and Herbert "Herb J" Jackson, is credited with having been the first to use the TB-303 in the house music context (the instrument appeared as early as 1983 in disco via Alexander Robotnick). The group's 12-minute "Acid Tracks" was recorded to tape and was played by DJ Ron Hardy at the Music Box, where Hardy was resident DJ. Hardy once played it four times over the course of an evening until the crowd responded favorably. Chicago's house music scene was suffering from a massive crackdown on parties and events by the police. Sales of house records were dwindling and, by 1988, the genre was selling less than a tenth as many records as at the height of the style's popularity. However, house and especially acid house was beginning to experience a massive surge in popularity in Britain.

In the late 1980s and early 1990s, news media and tabloids devoted an increasing amount of coverage to the hedonistic acid house/rave scene, focusing on its association with psychedelic drugs and club drugs. The sensationalist nature of the coverage may have contributed to the banning of acid house during its heyday from radio, television, and retail outlets in the United Kingdom. The moral panic of the press began in 1988, when the UK tabloid The Sun, which only weeks earlier had promoted Acid House as "cool and groovy" while running an offer on Acid Smiley Face T-Shirts, abruptly turned on the scene. On October 19, the tabloid ran with the headline "Evils of Ecstasy," linking the Acid House scene with the new and relatively unknown drug. The resultant panic incited by the tabloids eventually led to a crackdown on clubs and venues that played Acid House and had a profound negative impact on the scene...
