I'd say that Dale Crover was the most talented musician in Nirvana, and he wasn't even in Nirvana. Just played drums on several tracks between Bleach and Incesticide.
I remember when hair metal couldn't sell out a free show. A bunch of old, fat women with too much hairspray and makeup are gobbling up tickets doesn't make them relevant.
I'd say that Tool and Aerosmith have had the kind of longetivity most of these bands can only dream of.
