I can go from one extreme to another, from playing at the Sydney Opera House on the Songbook tour to shows with Soundgarden at Voodoo Fest, all in a week.

When you're having a conversation with someone who, despite his brilliant medical career, says he's going to produce the film, you think, "How's he gonna do this? Is he insane, or is he really going to pull this off? It might be both." It's really amazing to see someone do what he's done.

I think it's important for fans to know that but if I'm doing something that inspires me musically then I think it will inspire someone else too.

Sometimes, if a song is written, in essence, to be that stripped down, it's very touchy when you start adding things, because even the smallest thing can have a huge impact. Somebody has to make the decision that there's a better song in there if there's less.

People don't realize how much fun it is to be depressed.

I don't care what people think of me or for what reason they think of me. I don't feel like I don't know who I am to the degree that I have to change my hair to create a new me.

Due to irresolvable personality conflicts as well as musical differences, I am permanently leaving the band Audioslave. I wish the other three members nothing but the best in all of their future endeavours.
