The Orchestra Now (TŌN), conducted by Leon Botstein, performs works by one Turkish and two Hungarian composers. The concert begins with Turkish composer Ahmed Adnan Saygun’s Fourth Symphony, which contains a muscular, surging energy. This is followed by László Lajtha’s tragic “Revolution” Symphony, which commemorates the brutal suppression of the Hungarian Uprising of 1956. The orchestra is then joined by pianists Anna Polonsky and the Grammy Award-winning Peter Serkin for Bartók’s imaginative and colorful Concerto for Two Pianos, Percussion, and Orchestra.
