Album: Various artists, Freedom, Rhythm & Sound, (Soul Jazz)

As with previous Gilles Peterson compilations, there's a few tracks here that make you wonder whether he listened all the way through, but once past the dodgy vocals and workaday vamps, this two-CD collection of revolutionary US funky free-jazz contains real goodies.

The field has been well-mapped in recent years, not least by Soul Jazz, so many of the usual suspects are absent, leaving room for obscure choices by overlooked figures such as Horace Tapscott, Michael White, and the odd but perfect Gato Barbieri.
