Herbie Hancock Thrust (1974) [mastered By Kevin Gray, 2016]

The follow-up to the breakthrough Headhunters album was virtually as good as its wildly successful predecessor: an earthy, funky, yet often harmonically and rhythmically sophisticated tour de force. There is only one change in the Headhunters lineup – swapping drummer Harvey Mason for Mike Clark – and the switch results in grooves that are even more complex. Hancock continues to reach into the rapidly changing high-tech world for new sounds, most notably the metallic sheen of the then-new ARP string synthesizer which was already becoming a staple item on pop and jazz-rock records. Again, there are only four long tracks, three of which ("Palm Grease," "Actual Proof," "Spank-A-Lee") concentrate on the funk, with plenty of Hancock's wah-wah clavinet, synthesizer textures and effects, and electric piano ruminations that still venture beyond the outer limits of post-bop.
