Geoffrey Keezer was born on November 20, 1970 in Eau Claire, Wisconsin, where both his parents taught music. He began studying piano at age three. After attending the Berklee College of Music in Boston for one year, Geoffrey moved to New York City in 1989 to join Art Blakey's Jazz Messengers.

Since then he has worked with virtually all the living legends of Jazz, most recently completing three years on the road as the pianist with the Ray Brown Trio. Geoffrey has appeared on numerous recordings as a sideman and has released eight albums as a leader. The latest is an innovative solo piano CD entitled "Zero One" (Dreyfus/GMN). 1998's "Turn Up the Quiet" (Sony) featured Grammy-nominated vocalist Diana Krall along with Joshua Redman and Christian McBride. Geoffrey performed Gershwin's "Rhapsody in Blue" in 1992, with the Hollywood Bowl Orchestra conducted by John Mauceri, and has toured Japan and Europe with the opera singer Barbara Hendricks.
