Pomona has numerous singing and a cappella groups, including Men's Blue and White, Women's Blue and White, the After School Specials, the Claremont Shades, Midnight Echo, the 9th Street Hooligans, Kosher Chords, and Mood Swing. It hosts the annual SCAMFest concert, which also draws in a capella singers from other Southern California universities, as well as the regional quarterfinals for the International Championship of Collegiate A Cappella. Other musical groups include the Pomona College Orchestra, Band, Choir, Glee Club, Jazz Ensemble, and Balinese Gamelan Ensemble. All Pomona College students, and Claremont College students in Pomona College ensembles, can receive private music lessons at no cost. The Pomona College Theater Department leads 3–4 mainstage productions each year, and there are a number of smaller student-run productions as well. The college also hosts two improv groups, Without a Box and Underground Theatrical Institute (UTI).
