Earlier this year, flutist-saxist Anna Webber released Percussive Mechanics, a set of whimsical yet exacting tunes likely to strike a chord with fans of the Claudia Quintet. Tonight Webber gigs with the leader of that very group, John Hollenbeck, on drums and Matt Mitchell on piano. Saxist Curtis Macdonald opens with his groovesome, rhythmically complex postbop.
