Gershwin’s Concerto was premiered on December 3, 1925, in Carnegie Hall – the epicentre of New York’s classical music scene. It belongs to a group of self-imposed “experiments” with which the composter sought to make inroads into “serious” music: “I have only written three ‘opuses’ so far – ‘The Blue Monday Opera,’ ‘The Rhapsody in Blue’ and the ‘Concerto.’ I have devoted much time to these works, but they are, of course, not my regular work. They are experiments – laboratory work in American music.” For his edition, Norbert Gertsch reviewed a multitude of autograph and printed sources in the USA and for the first time presents an Urtext edition of this very popular piano concerto suffused by the jazz idiom.
