Zac grew up studying classical and jazz piano and trombone, and eventually branched out into playing trumpet, guitar, bass, and singing. An incredible talent, Zac was accepted into Berklee College of Music and awarded multiple scholarships at the early age of 16, but deferred until he graduated from High School.  Over the years, Zac has performed, written, and recorded across a diverse range of genres, including jazz, classical, pop, rock, punk, neo-soul, hip-hop, and reggae.
