I love playing. If it was down to just that, it would be utopia.

Once I got a guitar that was relatively user-friendly, but not super-duper easy, I really came on as a guitarist, at that point. It helped. It was a super-expensive guitar either, but something needs to steer you a bit, if you're playing an instrument that is really hard.

Well, Led Zeppelin IV! That's it really. I'll tell you why the album had no title - because we were so fed up with the reactions to the third album, that people couldn't understand why that record wasn't a direct continuation of the second album. And then people said we were a hype and all, which was the furthest thing from what we were. So we just said, `let's put out an album with no title at all!' That way, either people like it or they don't... but we still got bad reviews!

There's such a wealth of arts and styles within the guitar... flamenco, jazz, rock, blues... you name it, it's there. In the early days my dream was to fuse all those styles. Now composing has become just as important.

I bet you can't play slide piano.

Artists say that paintings are never done. I sort of feel the same way about music. I would never say something is perfect. There are performances that can generate a lot of emotion in me when I hear them, but I can't say if anything is perfect.

You never knew what was going to happen in concert. It was a really exciting prospect to go onstage, and you can hear that in the live recordings ... wherever we were and whatever year it was, we always went onstage determined to do our best.
