I stopped doing drugs when I was 20. I was finished with drugs before Nirvana even started.

Through Kurt I saw the beauty of minimalism and the importance of music that's stripped down.

When I joined Nirvana, I was the fifth or sixth drummer - I don't know if they'd ever had a drummer they were totally happy with. And they were strangers. There was never much of a deeper connection outside of the music.

I'm kind of claustrophobic... It's not even like enclosed spaces. It's like I hate being stuck in one band, you know? Just being stuck is the biggest drag, for fear that, you know, just that you can't get out.

You can make yourself the greatest singer in the world or the best drummer in the world with the aid of technology.

Guilt is cancer. Guilt will confine you, torture you, destroy you as an artist. It's a black wall. It's a thief.

I owe everything to Nirvana. But I can't let that overshadow the future. For the first few years, I didn't even want to talk about Nirvana. Partly because it was just painful to talk about losing Kurt but also because I wanted the Foo Fighters to mean something.
