Born in Bridgeport, Connecticut, and raised in Fairfield, he attended Berklee College of Music in Boston. He moved to Atlanta in 1997, where he refined his skills and gained a following, and he now lives in Montana. His first two studio albums, Room for Squares (2001) and Heavier Things (2003), did well commercially, achieving multi-platinum status.
