Venue: Nourse Theatre, San Francisco

A battle has been raging among the audiences of San Francisco concerts, and the conflict came to a head Sunday night at the Nourse Theatre. There were jeers and hisses and contempt lobbed into the air. But it was not the Juilliard String Quartet they were angry with. It was each other. The Juilliard was busy breathing life into one of Beethoven’s lesser works, his String Quartet No. 2.
