Improvisation is risky. I like that. Another practical reason for that is that you have to go out and play every day on a tour. I couldn't do it if I thought I was going to do the same songs every day in the same order, like a full-on robot.

I just throw myself into a mad frenzy, whip up a storm and see what comes through.

All kinds of music comes out that I'm not prepared for. Some of it is good, some of it rubbish, but I kind of accept it all. That's the nature of stream-of-consciousness. You can't always come up with your most lucid material in the heat of the moment. I take that risk when I play live. I open up my mind, however fertile a creative springboard it is that evening.

Improvisation has been with me since I was a kid, and, taking a selfish pleasure from that, I just thought, "What the hell. It might as well be something other people enjoy."

The layering of sound is by no means a two-dimensional process. Even though I've been doing it for a number of years, the diversity of it is so intriguing. It's a bit like traveling across the water. Though you may have done it time and time again it always hits you in a different way.

It's really hard to make something that doesn't sound like everything else.

If I don't keep my music varied I go a bit stir crazy, you know? If I don't have the opportunity to jump genres every now and again I feel I'm boxed-in.
