yeah, what Inc said, because if you notice, when Korn, Deftones, Limp Bizkit etc. started blowing up Cobain was gone, Alice In Chains and Soundgarden were on the verge of going extinct, Pearl Jam started to stray away from grungy sounding rock and what not (those 4 to me were the main hub of grunge, btw, maybe im wrong)...so I wouldn't say it necessarily died, it just evolved, if you can call Nu-Metal evolution, maybe more like regression...
