Is there more new Nirvana on the way?

Nirvana Scraps Still Left, Says Garbage Drummer Butch Vig
Butch Vig, who produced Nirvana’s classic album Nevermind, didn’t work on the single “You Know You’re Right,” but he did say he was glad the Scott Litt-produced track was released. Vig also added that “You Know You’re Right” was the best, but not the last, of Kurt Cobain’s unreleased music.
“It’s a great song. I mean, the first time I heard it, a chill went down my neck. It’s like, I heard Kurt’s voice again and, I miss him. I mean, he’d still be making great music if he was out here,” said Vig. “It’s a shame that there’s…that’s like, maybe, the last great track. There’s still a few raw things that I know haven’t come out yet. But there’s not a lot of stuff left out there that is as good as that. So I think it’s great. You know, I worked on that boxed set that got put on the table and there’s some really cool stuff on that–a lot of weird outtakes, some jams, and some acoustic demos–and I hope that comes out sometime in the near future.”
Butch Vig is working on a new album with his own band, Garbage. Vig has also produced records for Sonic Youth and Smashing Pumpkins.
