The Metro Chamber Orchestra begins its Sixth season with two glorious staples of the classical literature. Christopher Vath returns to the piano to join Artistic Director Phil Nuzzo and the orchestra in the Piano Concerto No. 5 “the Emperor” by Beethoven. Metropolitan Opera artists Sherry Zannoth and Noah Stewart join members of the Rockland Choral Society and the Metro Chamber Orchestra in Philip Hagemann’s arrangement of Claude Debussy’s “L’Enfant Prodigue” to round out the program.
