Berkeley Symphony Orchestra. The Berkeley Symphony Orchestra rose to prominence under Kent Nagano's baton and continues to prosper with Joana Carneiro at the helm. The emphasis is on 20th-century composers. The orchestra plays a few concerts each year, in the University of California–Berkeley's Zellerbach Hall and elsewhere in Berkeley. The acoustics in Zellerbach Hall are poor; sit in the front or middle orchestra for the best sound. 510/841–2800. www.berkeleysymphony.org.
