32. Herbie Hancock, 'Head Hunters'
Jazz keyboardist Herbie Hancock began the Seventies by cutting a heady trio of electronics-laden albums, backed by a volatile sextet. For Head Hunters, he eased up on the mood and made an ultra-groovy funk odyssey that kicked off with a burbling, riffy 15-minute jam perfect for some heavy-lidded wiggling. The album went on to sell a half-million copies, which is an awful lot of black-light soirées.
