Album: Nat Birchall, Sacred Dimension (Gondwana)

It can be argued that Mancunian self-taught saxophonist Birchall is a Coltrane copyist stuck in the run-off groove of 1960s spiritual jazz.

But, hey: it works for me. Birchall's music also continues to develop in a way that "frozen" forms shouldn't, and this third album is his most satisfying yet, with a looser, perhaps more folkily English feel. Rachael Gladwin's harp and Adam Fairhall's piano once again offer essential support, and Corey Mwamba guests on vibes.
