The Chamber Choir, under the direction of Robert Istad, is comprised of upper class members selected by audition. In recent years, they have become recognized as a premier collegiate vocal ensemble performing for numerous choral conventions including the American Choral Directors Association. The group has joined with the University Singers performing with the Hollywood Bowl Orchestra and the Pacific Symphony Orchestra among others, and in February 2003, the choir was selected as one of 42 choral ensembles to perform at the ACDA National Convention in New York presenting concerts at Riverside Church, Carnegie Hall and Avery Fisher Hall. Tours have included performances in Italy, Spain, Germany, and most recently, Australia.
