Indian electronic innovator Charanjit Singh has died.

The pioneering musician passed away at his home in Mumbai on Sunday, July 3. Singh was a cult figure in the music world following the rediscovery and re-release of his 1982 album Ten Ragas to a Disco Beat in the 2000s.

Singh was an unwitting pioneer of acid house music, credited with inventing the squelchy sounds that would come to signify the Chicago acid house sound in the years to come.

Veteran of countless Bollywood soundtrack orchestras, Singh purchased a Roland Jupiter-8 keyboard, a Roland TR-808 drum machine and a Roland TB-303 in 1982 and decided to make a record that blended traditional Indian ragas with western dance music. Ten Ragas to a Disco Beat was recorded in two days and was a largely forgotten commercial flop until it was reissued by record collector Edo Bouman in 2010.

The Wire reports that the 75-year-old guitarist and keyboardist died in his sleep. He had been preparing for an upcoming show in London and was planning to produce an album of Indian folk music.
