I was at a New Year's Eve party, and someone asked me how was my year, and I said, 'I honestly think 2011 was the best year of my entire life,' and I actually meant it.

You know, Nirvana used to start rehearsals with the three of us just jamming. For, like, a half an hour, just noise and freeform crap - and usually it was crap. But sometimes things would come from it, and some songs on Nevermind came from that, and 'Heart Shaped Box' and stuff on 'In Utero' just happened that way.

You know why Foo Fighters have been a band for 20 years? Because I've never really told anybody what I think of them. The last thing you ever want to do is go to therapy with your band.

There's poetry in being the band that can sell out Wembley but also makes a record in a garage. I don't like doing what people expect me to do.

I love Black Sabbath. They made an amazing contribution to music today. Almost every band that made it big in the Nineties owed a debt to them.

Chicago gave me more music than any other city in America.

When you're thirteen and listening to punk, the aggressive nature of music can sway you to the dark side.
