What better guide to the music of Duke Ellington than Wynton Marsalis? And here he is doing it live, improvised on WNYC. On Monday's show, Marsalis was on to discuss the history of NYC Jazz (and why so many Jazz greats are buried at Woodlawn Cemetary), and Brian played him a bunch of great music by local legends. Here's our favorite moment, when Wynton walks us through Duke's "Concerto for Cootie" and lead trumpeter Cootie Williams' inimitable style. You'll also hear from Woodlawn historian Susan Olson. Be sure to listen to the full segment here.
