Alot of people (in our circle) hate nirvana for killing the whole "hair band" "guitar hero" thing. But when you look back on the rock scene of 1990 and early '91 there really wasn't much to left to kill. It had kinda burnt itself out already. And any guitar heroes still around deserve to be because their success (as limited in scope as it might be compared to marketed trash) is attributable to staying power and fan bases.
