Even Miles Davis was envied of Herbie Hancock for the phenomenal success of Head Hunters. Davis started the fusion movement, but only a few understood his musical direction at the time. With the mega hits of “Chameleon” and “Watermelon Man,” Hancock proved not what an instrument could do for him, but what he could do with it. Over the funk-out groove, Hancock cooks up some of the most luscious solos on his electronic devices. From the funkified bassline to the jazz solos in double time, “Sly” is a damn fine tribute to Sly Stone. No wonder this breakthrough album had put Hancock on the map of avant-garde fusion.
