The Cal Poly Choirs will present the second annual “Holiday Kaleidoscope” at 3 p.m. Saturday, Dec. 1, in the Performing Arts Center. Cal Poly’s PolyPhonics, the University Singers and Chamber Choir will be joined on the concert by three local high school choirs: Cabrillo (Lompoc), Morro Bay and San Luis Obispo. Additional special guests will be featured, including string and brass players, a guest speaker and something especially for children in the audience. The Cal Poly Choirs will perform works by Wolfgang Amadeus Mozart, Dieterich Buxtehude, Herbert Howells, Eriks Ešenvalds and others, as well as various arrangements of popular carols and seasonal tunes. The combined forces of the university and high school choirs will perform Daniel Pinkham’s exciting “Christmas Cantata” for brass ensemble, organ and choir. Audience members can participate in a carol sing-along, and enjoy fun-spirited “cameo” pieces. Cal Poly staff member Paul Woodring will accompany the choirs on piano and organ. Jennifer Peterson conducts the Cabrillo High School choir, Holly Banfield conducts the Morro Bay High School choir, and David Alm conducts the San Luis Obispo High School choir. Scott Glysson is Cal Poly’s director of choral activities. Tickets for the concert are sold at the Cal Poly Ticket Office, 805-756-4849.
