Sylvester Stewart; radio DJ, small-time rock producer in San Francisco; started Sly and the Family Stone, late 1960's, fusing rock, soul music, and funk. Culture hero of sorts, in the way that Dennis Rodman is today. Got married onstage at Madison Square Garden during a gig. Behavior often erratic, due to excessive drug input (Keith Richards? Amateur!). Played most of the instruments on There's a Riot Goin' On, one of the darkest "pop" (ha!) LPs ever.
