Brett Carson is a composer, pianist, improviser, poet, and theater artist based in Oakland CA. His compositional work, which has been described as "fascinatingly intense" (Stephen Smoliar, SF Classical Voice), explores the juxtaposition of a gleefully chaotic plurality of musical approaches.  In addition to his compositional work, he enjoys a career as a pianist, keyboardist, and synthesist, having performed internationally in the realms of free improvisation, contemporary classical music, jazz, and rock. He has worked with a wide variety of composers/performers including Bill Baird, Brian Baumbusch, Nicolas Collins, Vinny Golia, George Lewis, Nicole Mitchell, Roscoe Mitchell, Bill Noertker, Zeena Parkins, Rent Romus, and William Winant. From 2019-20, he performed as the pianist for the legendary jazz unit the Art Ensemble of Chicago.
