Looking for something civilized to do on April Fool’s Day? Then consider attending a late afternoon Baroque music concert by Judith Linsenberg. Audiences throughout the United States and Europe have heard Lisenberg play her recorder, including solo appearances at the Hollywood Bowl and Lincoln Center. You’ll be able to hear her at the Northbrae Community Church in Berkeley this Sunday. It’s a benefit for the Early Music society known as Music Sources, which is dedicated to “historically informed performances of western classical music.” The concert begins at 5pm.
