A Crowden 40th Anniversary Alumni Concert!

Join us for an afternoon of music with the Baumer String Quartet, an extraordinary string quartet with local roots, featuring three globally acclaimed players who went to middle school together at The Crowden School in Berkeley: Phoenix Symphony violinist Aaron Requiro, his younger brother, Naumburg International Violoncello Competition winner cellist David Requiro, and Dallas Symphony co-concert master Nathan Olson. Acknowledged as one of the finest young quartets in the country, the Baumer String Quartet distinguishes itself among audiences and critics for its technical finesse, warmth of expression, and cutting-edge performances.
