It’s impossible to overestimate the impact that Edward Kennedy “Duke” Ellington (born April 29, 1899) had on jazz and indeed the world of music in general. Even if his myriad contributions to the Great American Songbook were his only accomplishment, he would be one of its most hallowed creators, but his legacy is far more sweeping. He managed to field an orchestra for several decades consisting of totally unique musical personalities for which he tailored new compositions to feature their individual and combined strengths in a way that was completely original and influenced literally everything that came after him.
