As a result of the instantaneous success of his 'Rhapsody in Blue' for Piano and Orchestra, Gershwin was commissioned to write a three movement Piano Concerto - a severe test for him as for the first time he had to come to grips with a serious musical form. Gershwin succeeded magnificently, as has the arranger Carlo Martelli in reducing the third movement of this masterpiece down to four string players. For colleges, conservatories and professionals.
