IoS album review: Nat Birchall, World Without Form (Sound, Soul and Spirit) In a scene dominated by jazz graduates who are fluent in the language but don't have much to say, the music of saxophonist Birchall - who came to Coltrane via reggae's Cedric Brooks - screams "Belief!" This latest release invests spiritual jazz with a personal vision evoking space and soul. Doubling up bass and drums creates a thicker sound, with roles for Corey Mwamba, Jon Thorne and Paul Hession. Regular pianist Adam Fairhall is a total star.
