In 1929, America enters a decade of economic desperation, as the Stock Market collapses and the Great Depression begins. Factories fall silent, farms fall into decay, and a quarter of the nation's workforce is jobless. In these dark times, jazz is called upon to lift the spirits of a frightened country, and finds itself poised for a decade of explosive growth. New York is now America's jazz capital. Louis Armstrong revolutionizes the art of American popular song. In Harlem, Chick Webb pioneers his own big-band sound at the Savoy Ballroom. Pianists Fats Waller and Art Tatum dazzle audiences with their stunning virtuosity. Duke Ellington composes hit tunes with a new sophistication that has critics comparing him to Stravinsky. Benny Goodman is making a name for himself, broadcasting big-band jazz nationwide, based on Fletcher Henderson's arrangements.Produced by Ken Burns. DVD includes music information cards. .
