I had a look at the tv last night and I was changing channels and there is one children's channel that plays jazz overnight and then switches to childrens programs for the day, and I hear the middle of a line solo and within 2 seconds I'm thinking it sounds like George Benson and then about 10 seconds later I hear these dissonant blues cliches and I know it's the Cooker. All of the great players can be id'd very easily, Django etc and also in Rock and Classical (I can id John Williams or Julian Bream pretty easily) etc etc. I can always id Django as compared to his clones. There was a time where I was taking Django stuff note for note but I gave it up after a few months because I didn't want to be an inferior Django clone and the main target for me was to learn things off of Django's playing and not be a Django clone. The rest of us exist in a generic way as far as our playing goes. What it actually is who knows, personality, a lot of things.
