The flowering of the Jazz Age is a tale of two great cities, Chicago and New York, and two extraordinary artists whose achievements spanned nearly three-quarters of a century. Louis Armstrong was a fatherless waif who grew up on the rough streets of New Orleans, developing his extraordinary gifts before moving to Chicago, where his transcendent sound inspired a new generation of musicians. Duke Ellington, raised in middle-class comfort, outgrew the society music of Washington, D.C., and headed for Harlem, where he formed a band and created a music all his own.
