Curtis Mayfield, Rock and Roll Hall of Fame and Museum. "…significant for the forthright way in which he addressed issues of black identity and self-awareness. …left his imprint on the Seventies by couching social commentary and keenly observed black-culture archetypes in funky, danceable rhythms. …sounded urgent pleas for peace and brotherhood over extended, cinematic soul-funk tracks that laid out a fresh musical agenda for the new decade."
