Vox Pop....

Bang

"I was only in Nirvana for six months before they signed to Geffen, they had five other drummers before me. When I joined it was something that was being talked about [moving to a major label], but as far as we were concerned, the second album was gonna come out on Sub Pop. Nirvana had written a contract with Sub Pop; I think they might have been the only band who did.
  There was a lot of stuff recorded at that time that has never been heard. Everybody knows Nirvana from 1991 onwards, but nobody knows Nirvana from 1986 to 1991 and that was the foundation of what Nirvana eventually became with Nevermind. There's some pretty cool shit yet to be released.
  To see the foundation of that conventional rock format come from something fucked up - it was coming from the Butthole Surfers and Scratch Acid and Creedence Clearwater Revival, music that the majority of Nirvana fans aren't familar with....they were very creative people."
