Last concert tonight in Berkeley. Here's Joshua Kosman's review. After tonight we'll leave our orchestra friends at home and go back to our a cappella selves and get on the plane for Portland, Oregon, La Jolla, California, Palm Desert, California, Purchase, NY, New Britain, New Canaan and Darien, Connecticut, Cincinnati, Greencastle, Indiana, and Joliet and Peoria, Illinois. Our spring touring tends to take us from one end of the country to the other and in between, and any number of possible climates.
