Tom Baker (guitar, fretless guitar), drummer Greg Campbell, clarinettist Jesse Canterbury and bassist Brian Cobb have diverse musical backgrounds, which include jazz, modern classical, world music, and free improvisation. They have been working as a quartet since November of 2004, playing music by Baker and Cobb, as well as crafting beautiful and haunting improvisations. Their music blurs the boundaries between notated music and free improvisation; the unique sonic landscapes that result are grounded in history, while pushing at the boundaries of avant-jazz music
