Isn't one problem that the average person associates the term 'jazz' with the kind of low-energy music performed by the Kenny G's of the world? Basically background music, in the minds of many folks.
Or maybe just as bad, Wynton retooling material that's a half century old.
I'd say that a band like Reptet, for instance, that plays a kick-ass brand of music that people can move to in a club, isn't the first thing that pops into most folks' minds when you utter the term 'jazz.' And for those who might respond, "Well, that isn't strictly speaking jazz," there you go.
