It's been five years since Michael Francis has been in town to work with your Rochester Philharmonic Orchestra, and he's returned for a concert of just two pieces...but those pieces are mighty. In the first half, Sir William Walton's searing Symphony No. 1, with Rachmaninov's Piano Concerto No. 3 featuring Van Cliburn Gold medalist Yekwon Sunyoo in the second half. Maestro Francis stopped by to chat with Julia Figueras about the two works and the universal language of music.
