Duke Ellington - 1934, 35

At the dawn of the Swing Era, Ellington was in a bit of a funk . . his recording opportunities were less and the Depression had limited opportunities.  Fortunately, his creativity came back quickly, mostly in answer to the swing style beginning to establish itself.  With a band including Cootie Williams, Rex Stewart, Lawrence Brown, Joe Nanton, Juan Tizol, Barney Bigard, Johnny Hodges, Harry Carney, Otto Hardwick, Wellman Braud (replaced by both Hayes Alvis and Billy Taylor), Sonny Greer and Ivy Anderson, he always sounded like himself.
