We're kind of an international phenomenon.

Once I reached my 40s, I thought to myself that if I'm going to play live now, I need to really mean this. I can't go out and be a little bit, for one moment slovenly in my choices as a performer. I mean, these people have paid a lot of money to be here, they've been through the nightmare of getting here, starving themselves waiting for us to get on stage, so I'm going to give them what they came here for.

But I think the one thing that I can say about us is that we're very consistent about certain things and part of that is our desire to do the very best work that we can and not rest on our laurels, or not allow formula to come into what we do.

Sometimes I'm confused by what I think is really obvious. But what I think is really obvious obviously isn't obvious.

I knew [Kurt Cobain] and his daughter. And Courtney [Love] came and stayed at my house. R.E.M. worked on two records in Seattle and Peter Buck lived next door to Kurt and Courtney. So we all knew each other. I reached out to him with that project as an attempt to prevent what was going to happen.

By the time I was 18, I had absorbed punk rock from America, Britain, and the West Coast. All of it was so dark and weird and different and cool and hot and sexy and rebellious. It was a fist-in-the-air kind of rebellion that I wasn't getting from the '70s mainstream.

So, when you divide the world into music lovers, music fans and then those people who are just very casual about their music, it's wallpaper to them, it's elevator music, it's just the thing that's playing in the background that helps them through their day.
