Before Sly Stone became the psychedelic soul architect behind Sly and the Family Stone, he was already breaking barriers behind the mic and behind the boards. In the mid-1960s, Stone was a DJ at KSOL in San Francisco, curating playlists that blurred color lines—mixing The Beatles and The Rolling Stones into soul-heavy sets. At a time when radio was often segregated by genre and race, Stone spun unity. He dubbed the station “K-SOUL” and made it a beacon for music that moved the mind, body, and, yes, the soul.
