I understand your doubts about the nirvanathing. I think Curt had a great voice and was special in that kind, the music was great and the lyrics too. I think the same way about the sex pistols. They were good but if they were three months later they would be just one of the great punkbands.
It’s a shame that music critics do have a lot of influence on the big public; we as Indie-followers feel that in particular because we feel indie. Nice topic btw.
