Saxophonist Guionnet guides this quartet of sax, viola, cello, & percussion, including label leader Ernesto Rodrigues, delicate yet detailed improv of a high order.

Violinist Gerszewski developed an individual form of notation to create his "ordinary music", a continuation of abstract visual thinking by means of sound.

Excellent, fun and slightly twisted free improvising quintet with Dennis Gonzalez, Mark Sanders, Alipio Netom, and father/son team Ernesto Rodrigues and Guilherme Rodrigues.
