I think YYZ has it right, here, Chitz. It's not that one necessarily affects the other, but rather that each piece is an elaboration on a complex whole. That is to say, style of dress, musical taste, idiosyncrasies of dialect, are all borne out of the same whole. I don't mean to say it's nature or nurture, but these are all just forms of expression.
And as always, there are exceptions.
I've been known to play a jazz show in a Hanoi Rocks t-shirt. Anybody remember that band, now? Some people wear suits and then go out and dress up like GWAR for shows.
(Btw, fun fact, GWAR, by day, is a five piece jazz combo. They just play under a different name. Awesome, huh?)
