Since 1967, students and staff jazz musicians have had an opportunity to perform and study with the University of California Jazz Ensembles. Under the direction of Dr. David W. Tucker, who was hired by the Cal Band as a composer, arranger, and associate director, but was later asked to direct the jazz ensembles as it grew in popularity and membership, the group grew rapidly from one big band to multiple big bands, numerous combos, and numerous instrumental classes with multiple instructors. For several decades it hosted the Pacific Coast Collegiate Jazz Festival, part of the American Collegiate Jazz Festival, a competitive forum for student musicians. PCCJF brought jazz luminaries such as Hubert Laws, Sonny Rollins, Freddie Hubbard, and Ed Shaughnessy to the Berkeley campus as performers, clinicians, and adjudicators. The festival later included high school musicians. Michael Wolff and Andy Narell are just a couple of its more famous alumni.
