On October 6, 1939, four orchestras gathered at New York's Carnegie Hall to celebrate the 25th anniversary of ASCAP. Last on the bill was Glenn Miller. The audience had already experienced the music of Benny Goodman, Fred Waring, and Paul Whiteman when Miller and his group took the stage, but Miller made the audience completely forget about the previous three outfits, captivating listeners at every turn. He lead his orchestra through a program of music that ranged from full-scale swing to soft and romantic. It was a night that critics quickly hailed as Miller's defining moment. That legendary performance is today available on CD. The Carnegie Hall Concert is a must for any avid Miller fan.
