I'm self-sufficient. I spend a lot of time on my own and I shut off quite easily. When I communicate, I communicate 900 per cent, then I shut off, which scares people sometimes.

I just feel like making things solar-powered and wind-powered should be as easy as using an iPad.

When I met Apple, I made it very clear that I am an old punk and I have never done commercials or been sponsored. And I wasn't after their money.

When I write a song, I see a tunnel, and then the chorus is an open space, or the bassline is doing this shape. I see songs as a more of a geometric, spacial experience.

But I'm not interested in politics. I lose interest the microsecond it ceases to be emotional, when something becomes a political movement. What I'm interested in is emotions.

I feel the 21st century is another new age. Not only can we collaborate again with nature, but we have to. It's an emergency.

I mean, I've never been thinking that if you're a fan you have to buy everything that somebody puts out. I mean, you've got a choice. If you don't want it, just don't buy it. It's also a reaction to YouTube and sharing of files. A lot of it is really bad sound, really low quality. So the librarian in me wants it at least to exist there so that in 20 years when I'm sitting in my rocking chair, it will still exist in the best sound quality possible, even though it only sold 1000 units or whatever. As much as I love the whole pirate kind of thing, the quality suffers.
