How Acid House Was Born by Accident

Some genres are designed. Acid house was discovered by mistake. It began with a machine nobody wanted: a small silver Roland box built to imitate a bass guitar, then quietly discontinued. A few years later, three teenagers in Chicago bought one second-hand, never learned to program it, and stumbled onto the sound that would name a genre, acid house.

The Roland TB-303 arrived in 1981, designed by the engineer Tadao Kikumoto, who also created the TR-909 drum machine that would later power house and techno. Roland marketed it as a computerised bass machine, a practice tool meant to stand in for a bass player and pair with the little TR-606 drum unit.

There was just one problem: it sounded nothing like a real bass, and it was notoriously hard to program. It flopped. Roland discontinued it in 1984 after only around ten thousand had been built, and the unloved machines drifted into pawn shops and bargain bins. That is where a few of them reached the hands of Chicago kids.

In 1985, three friends formed a group called Phuture: Nathan Jones, who DJed as DJ Pierre, Earl Smith Jr., known as Spanky, and Herbert Jackson, or Herb J. Spanky picked up a second-hand 303 for next to nothing, and none of them had any idea how to program the thing.

As Pierre later told Red Bull Music Academy, he simply started twisting knobs while Spanky urged him to keep going; an hour or two later, almost by accident, they had built their first track. He has put it more bluntly since: the record came out of pure ignorance, of not knowing how the machine worked. By sweeping the filter cutoff and resonance while the sequencer rolled, they coaxed out a squelching, liquid, resonant tone that no one had ever made the centre of a song.

The track was first called In Your Mind, and it found its true home at the Music Box, the harder and wilder successor to the Warehouse, the club where Frankie Knuckles had given house its name. Phuture handed a cassette to the Music Box resident, Ron Hardy. The first time he played it, the floor emptied. He played it again, and again, across the night, until by the final spin the room detonated. Dancers began swapping bootleg cassettes labelled Ron Hardy's Acid Track, and the nickname stuck.

Unsure how to turn a tape into a record, Pierre slipped a handwritten note to the house star Marshall Jefferson, who was then doing A&R at Trax Records. Jefferson agreed to help and slowed the tempo for floors beyond Chicago, and in 1987 the track appeared on vinyl as Acid Tracks. Exactly how much Jefferson shaped the record is disputed, since he and Pierre remember his role differently, but the outcome was the same: the defining acid house record was out in the world. Phuture were reportedly paid a modest flat fee and had no idea their accident had already lit a fuse across the Atlantic.

The name itself is genuinely contested. The most repeated story traces acid back to that Music Box tape nickname. Pierre has given more than one account over the years: sometimes that it nodded to the LSD circulating in the club, other times that it simply described the mangled, acidic tone of the 303 rather than any drug. A rival British theory claimed acid came from acid burning, slang for theft, aimed at house music's appetite for sampling. No single version is definitive, which feels right for a sound nobody set out to invent.

Acid house might have stayed a Chicago secret if not for Ibiza. In the summer of 1987, a small group of British DJs, among them Paul Oakenfold and Danny Rampling, fell for the island's clubs and the loose, ecstatic feeling of its dancefloors, and they carried it home. Rampling's night Shoom, Oakenfold's Spectrum and a handful of others turned London into something new, and by the summer of 1988 the whole country was caught up in what became known as the Second Summer of Love, grinning yellow smiley and all. In Manchester, the Haçienda spread the gospel north.

The British press could not make up its mind. One week the tabloids were selling smiley T-shirts; the next they were warning about the evils of ecstasy. When D-Mob's We Call It Acieed stormed the charts, the BBC began pulling songs that so much as mentioned acid from the airwaves. The crackdowns backfired, pushing the parties out of licensed clubs and into warehouses and fields, where they seeded the illegal rave scene and, before long, a wave of anti-rave laws.

The instrument Roland could not give away turned into a holy grail. Second-hand prices that had once sat under a hundred dollars climbed past a thousand as producers chased the squelch, and a small industry of clones and reissues grew up to feed the hunger. The sound fed entire offshoots, acid techno and acid trance among them, and kept resurfacing on hits for years; one of Fatboy Slim's earliest singles even carried the title Everybody Needs a 303. Kikumoto, who designed the machine, later admitted that its famous acid tone was never the sound he had been aiming for, but that he had deliberately left the synth open enough for users to discover it. The failure had become a classic.

• Acid house grew out of the Roland TB-303, a bass synth that flopped and was discontinued in 1984.
• Chicago's Phuture, DJ Pierre, Spanky and Herb J, found its squelchy sound by accident while twisting the 303's knobs.
• Ron Hardy's plays at the Music Box gave the track its acid nickname, and Acid Tracks was released on Trax in 1987.
• Ibiza carried the sound to Britain, fueling the 1988 Second Summer of Love and a tabloid moral panic.
• The once-unwanted 303 became one of dance music's most coveted and cloned instruments.
