Matthew Bourne has found something of a soul mate in UK-based Norwegian drummer Emil Karlsen on this spiky and thoughtful set of improvisations that conjures an uneasy and powerfully unsettling atmosphere so effectively. Karlsen is a brittle, rugged foil to Bourne's quick-witted sleight of hand on a recording that never overstates itself and is full of twists and turns. If you are a free-improv fan, tired of the soft sweet centres you find on many a jazz record, then you'll be craving a case of this hardy and satisfying vintage made a couple of years ago and now ripe for extensive listening.
