Context: Acid house arose from Chicago artists' experiments with the squelchy Roland TB-303 bass synthesizer, and the style's origins on vinyl is generally cited as Phuture's "Acid Tracks" (1987). 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 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. The track also utilized a Roland TR-707 drum machine.
