Phuture is a Chicago-based acid-house group founded in 1985 by Spanky, DJ Pierre and Herb J. The group's 12-minute track "Acid Tracks" (1987) is one of several recordings that lay claim to being the first-ever acid house record.
"Acid Tracks" featured characteristic bass lines from the Roland TB-303 bass synthesizer—which was manipulated to produce resonant and squelchy sounds uncharacteristic for a bass guitar it was designed to emulate. The track rose to popularity at DJ Ron Hardy's Music Box club in Chicago and has since been re-pressed many times.
