Gershwin's Concerto in F was a work commissioned by Walter Damrosch in the spring of 1925. Gershwin began the two-piano score in July, titling the original drafts the "New York Concerto." It was performed first in December, 1925, with Gershwin at the piano and Mr. Damrosch conducting the New York Symphony Orchestra. This is the 1927 2-piano score, technically advanced in level of difficulty. Two copies are needed for performance. Two-piano edition, with second piano playing a transcription of the orchestration.
