The 4th volume in Brazilian/New York saxophonist Ivo Perelman's exemplary 6-part series "The Art of the Improv Trio" bring together bassist William Parker and drummer Gerald Cleaver for a 3-part set of free improvisation, beautifully flowing dialog of masterful playing.

An extended and passionate work from NYC saxophonist Ivo Perelman, recorded at a studio session intended as a trio with drummer Cleaver and pianist Shipp, but from a scheduling mixup, serendipitously evolved into a quartet with the addition of William Parker on bass.
