CGQ features Greene on tenor and soprano saxophone, Damian Espinosa on primarily acoustic piano (but also occasionally on electric keyboard), Marc Piane on acoustic bass and drummer Tyrone Blair. The CGQ has forged a unique sonic identity through the immediate personal chemistry these four remarkable musicians discovered when they first played together, and through subsequent steady work. In many ways, as Greene designed the band to be, they are a throwback to the classic Blue Note label jazz units - bands that featured stable personnel, hard-swinging and thought-provoking music, with a sensibility that was at one time rooted in the popular culture but was very definitely high-concept art; in other words, music for both body and mind.

The CGQ continues to be one of the busiest working bands in Chicago, performing regularly at places like M Lounge, Pete Miller's, Andy's Jazz Club, Red Kiva, and most recently at that holy grail of Windy City jazz joints, The Jazz Showcase. They are steadily earning a reputation as one of Chicago's most exciting ensembles. Greene is becoming known as one of the city's finest rising instrumentalists. Catch them locally while you can!
