The story behind
This song doesn’t sound like anything Herbie Hancock had recorded before. On Sly, the electric piano Fender Rhodes blends with percussion that jumps between African rhythms and funk grooves, creating a sound that seems to float between the organic and the electronic. The main melody, repeated with variations, doesn’t follow traditional jazz or rock structures. Instead, it’s built on a pulse that speeds up and slows down without warning, as if time itself were breathing. What stands out most is how the track dismantles and rebuilds itself with each repetition, with Hancock and his band playing with stretching silences before returning to the central riff, which sounds both familiar and completely new.
They recorded it at night at Wally Heider Studios and Different Fur Trading Co. in San Francisco, during the Head Hunters sessions. Hancock gathered musicians from different backgrounds: Bennie Maupin, who had already collaborated in his Mwandishi era, alongside Paul Jackson, Bill Summers, and Harvey Mason, who would later form the band Headhunters. Producer David Rubinson captured that raw, unedited studio sound, where even interpretive mistakes became part of the groove. The result was an album that sold over a million copies and became his biggest commercial success, but Sly in particular stood out for its blend of technical precision and improvisational freedom—something Hancock had explored before with Miles Davis but here brought to more accessible ground without losing depth.
