Sextant was dazzling, make no mistake about it, but with Head Hunters Herbie goes for a change of approach, injecting horse doctors' doses of funk into the mix, scaling back the more abstract space rock-inspired passages radically, and getting a new backing lineup to really bring the sound of the album together. Particular props have to go to Paul Jackson's bass work - a fat, meaty bass sound being absolutely vital to any funk undertaking - as well as the completely off the wall percussion work of Bill Summers, who brings a truckload of different instruments to bear. But more or less every performer has their moment in the spotlight here - Bennie Maupin's flute performances are a particular treat - and of course Herbie's synths and keyboards are a constant presence. It's a bit of an abrupt gear shift after the Mwandishi albums, but it's an undeniably successful one.
