Funk pioneer Sly Stone, a onetime San Francisco DJ turned pop music innovator and leader of Sly and the Family Stone, has died at 82.

Sly Stone died on Monday, June 9 at the age of 82, his family announced. The musician was best known as the leader of Sly and the Family Stone, the influential psychedelic soul and funk band that played Woodstock.

By November of the same year, Sly Stone seemed to pose an answer: “There’s a Riot Goin’ On.” At the time that album was released, Stone, who died this week, at the age of eighty-two, was facing a make-or-break career inflection point.
