My school band was onsessed with being Nirvana. Heady days. Great band, massive influence on me (I'm guessing I'm of the same vintage as Lucky - my mum bought me In Utero from Woolies when I was off sick from school), and still more exciting and visceral than 90% of rock music today. As for the "they couldn't play" argument, I must say I think it's complete bollocks. Writing tunes as consistently strong as Nirvana's takes real skill, and I'd always rather listen to Kurt's squall than any number of widdly metal mathematicians. Also, some of Dave Grohl's drumming circa In Utero is mindblowingly intense. He made me hate cymbal tickelers as much as Novoselic made me despise high slung bassists. Especially slap bassists. Urgh. So, yeah, Nirvana were fucking ace. All else is revisionism.
