I like to deal with my dark side in a creative way, and just sing about killing people instead of actually doing it.

I had brief glimpses of emotional catharsis while writing. I remember reading something Philip Roth wrote about how he writes every single day, but it's almost as if he has amnesia every morning - he has almost zero confidence that anything will come but he just sits down and plugs away. And at the end of the day it feels like a miracle: "How did I do that?" I had a similar experience where it was just about putting in the hours and being present.

I think every time I play, every show is different, and I think that at a certain point a song isn't about you anymore. It's about the audience, it's about how the song has worked its way into other people's lives and that kind of keeps the meaning of the song new, because you see it reflected in other people every night.

With the first kid, you micromanage it, making sure there's no hair out of place when it goes off to school. But by the third kid, it's more like, "Oh, you want to wear a splatter-painted, Hard Rock Café T-shirt for seven days in a row and not brush your hair? Go for it. Be who you want to be."

I was a lusty kid who loved Tennessee Williams. Sexy plays. [For musicians] there are so many that it's hard just to say one. Certain things, like the first time you hear A Love Supreme, you're floored. It takes whatever you were listening to and blows a hole in it.

I do love the ceremony of putting on a record but I don't have space for a vinyl collection.

CDs are usually an hour long because that's the amount a CD could hold - not because that's the optimal amount of time for any given musical expression.
