Well the Drops "image" seems to me to be ironic. I mean when you call your record "Genuine Negro Jig" or whatever and dress like they do you've got to be doing it with humour.
As to Kenny G-- why be sarcastic about him either? I've never heard him (actually I saw him do a number at the World Cup here a decade or so ago) and presume I wouldn't like him but I don't think that makes me superior to the many people who do like him. There's often a tendency for jazz fans to feel their taste is better than that of non-jazz fans, forgetting that most of the world thinks we're a bunch of nerds.
