Four treasured local artists treat us to a feast of sonatas. First we will hear a trio sonata by J.S. Bach featuring both violin and flute, and with Mr. Strong on the piano. Next, Peter Rovit, Symphoria's concertmaster, and Ida Tili-Trebicka, on the faculty at SU, will perform the beloved Franck violin sonata. Finally, Xue Su, principal flute for Symphoria, and Sar-Shalom Strong, who teaches at Hamilton College, will play the Prokofiev flute sonata, a masterpiece for the instrument.
