Classical musician known for his recording of George Gershwin's "Rhapsody In Blue" for Woody Allen's Manhattan from 1979.
He began studying under Isabelle Vengerova at the Curtis Institute of Music when he was seven.
His playing was challenged in 1979 after a sprain in the right ring finger, possibly caused by focal dystonia, forced him to stop using his right hand completely.
His parents were of Russian-Jewish origin. His talent for the piano became evident when he was three.
He and conductor Leonard Bernstein recorded Rhapsody on a Theme of Paganini by Sergei Rachmaninoff in 1964 with the New York Philharmonic.
