Can't say I was ever a huge fan. I can appreciate a few tunes but I've always thought they overshadowed a lot of more deserving and more talented bands of the grunge scene. Alice in Chains, Mudhoney, Soundgarden for example.
I wonder how Kurt would relate now though. I sometimes think it's a blessing in disguise when artists that hit such a cultural nerve that is specific to a time period, that they die in that time period. I don't think anyone would've wanted to see Kurt go on to make boring and irrelevant music while still trying to speak to a young and socially displaced audience when he was 45 years old.
