Despite its Southern black origins, there was a larger market for jazzy dance music played by white orchestras. In 1918, Paul Whiteman and his orchestra became a hit in San Francisco. He signed a contract with Victor and became the top bandleader of the 1920s, giving hot jazz a white component, hiring white musicians such as Bix Beiderbecke, Jimmy Dorsey, Tommy Dorsey, Frankie Trumbauer, and Joe Venuti. In 1924, Whiteman commissioned George Gershwin's "Rhapsody in Blue", which was premiered by his orchestra. Jazz began to be recognized as a notable musical form. Olin Downes, reviewing the concert in "The New York Times", wrote, "This composition shows extraordinary talent, as it shows a young composer with aims that go far beyond those of his ilk, struggling with a form of which he is far from being master. ... In spite of all this, he has expressed himself in a significant and, on the whole, highly original form. ... His first theme ... is no mere dance-tune ... it is an idea, or several ideas, correlated and combined in varying and contrasting rhythms that immediately intrigue the listener."
