Pacifica Quartet with Marc-André Hamelin

The plucky, persuasive Pacificas have been traveling in fast company recently, having played Zankel Hall not so very long ago with superstar singer Nathan Gunn. They're back tonight with another headline-grabbing musician, pianist Marc-André Hamelin, to perform Leo Ornstein's rarely encountered Piano Quintet; Beethoven's String Quartet in B-flat (Op. 130), with its original Grosse Fuge ending restored, completes the program.
