The Riverside Symphony's season opener, which starts at 8pm, includes the New York debut of Brett Dean's Testament. But thanks to the orchestra's new Hear Hear! program, you can also catch the piece at 7pm, adding to its impact the second time around. Mendelssohn's overture to The Fair Melusina, Mozart's Piano Concerto No. 17 (with soloist Benjamin Hochman) and Beethoven's Symphony No. 1 fill out the dance card.
