 Acid house originated in the mid-1980s in the house music style of Chicago DJs like DJ Pierre, Adonis, Farley Jackmaster Funk and Phuture, the last of which coined the term on his "Acid Trax" (1987).It mixed elements of house with the "squelchy" sounds and deep basslines produced by the Roland TB-303 synthesizer.As singles began to reach the UK the sound was re-created, beginning in small warehouse parties held in London in 1986–87.
