I see what you're saying dawg. Nirvana were pretty essential to my musical education, mainstream yes- but important. They were a gateway band- getting me off grindcore and into the Butthole Surfers, Polvo, GVSB, Husker Du, Sonic Yoof etc. Life changing moment in the sixth year common room and all that..... Were you into Smashing Pumpkin's and Pearl Jam? XX
