In terms of pure musicality, George Gershwin was America’s Schubert. He composed with a creativity and skill that immortalized his art, and hardly any of his works is more embedded in the world’s musical consciousness than Rhapsody in Blue, originally described by Gershwin as a “symphony” for piano solo and jazz band. This extraordinary chamber music program pays tribute to great composers who crossed the bridge between the classical and jazz idiom, with dazzling results.
