I'm not sure I really understand the question either, but otherwise I'm with Paul in that, when I first began listening to jazz (and even before), Duke was just another big band leader of the sort that my grandparents might have listened to. I quickly learned that wasn't the case, of course, and from that point on Ellington's music had a profound affect on me. My Holy Jazz Triumvirate is Duke, Monk, and Mingus, but more to the point is that once I discovered Ellington's music - even of the big band variety - it always struck me in ways that most big band music doesn't. Basie, Goodman, even Woody Herman (whom I've since grown to love) can barely touch Duke imo. Discovering Duke was almost like discovering jazz itself; it opened not just one but a whole series of musical doors.
