From 1917 through 1924 the "Jazz Age" begins with speakeasies, flappers and easy money for some. The story of jazz becomes a tale of two cities, Chicago and New York and of Louis Armstrong and Duke Ellington, whose lives and music will span three-quarters of a century. This episode also follows the careers of jazz greats James Reese Europe, King Oliver, Willie Smith, Fletcher Henderson, Paul Whiteman and James P. Johnson.
