Acid House

Acid house is a sub-genre of house music that emphasizes a repetitive, hypnotic and trance-like style, often with samples or spoken lines instead of lyrics. Acid house's core electronic squelch sounds were developed around the mid-1980s, particularly by DJs from Chicago, Illinois, who experimented with the Roland TB-303 electronic synthesizer-sequencer. Acid house spread to the United Kingdom and continental Europe, where it was played by DJs in the acid house and later rave scenes. By the late 1980s, copycat tracks and acid house remixes brought the style into the British mainstream, where it had some influence on pop and dance styles.

Nicknamed the sound of acid, the influence of acid house can be heard in subsequent styles of music that include trance, Goa trance, psychedelic trance, breakbeat, big beat, techno.
