Our concert at the Philadelphia Art Alliance on May 13 is part of our "Last Fridays" series, even though it's not the last Friday of the month. That means that it starts at 5:30, and admission is free. Also characteristic of the series is the format: about an hour of delightful chamber music. Featured this month are quartets by Haydn (Op. 42 in D minor) and Brahms (Op. 51, No. 2, in A minor). We hope you can join us!
