Phuture (nowadays called Phuture 303) is a Chicago-based acid house group founded in 1985 by Dj Pierre, Spanky, and Herb J (Herbert Jackson). Their 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 actually abused to produce sounds uncharacteristic for a bass guitar it was designed to emulate. The track raised to popularity at DJ Ron Hardy's Music Box club in Chicago and has since been re-pressed many times.
