Music can always be a life-changing experience, for musicians and fans, or at least life-affecting, but it depends on to what degree.

There is far more sensitivity in acoustic guitar players than could ever be compared to any synthesizer. That's a personal point of view but that's the way I see it. I think that's what it's all about. The drive, the fire, the passion - it all comes out on the guitar.

If you wanted to chart new territories and head off over the horizon, you had to make sure you weren't overly influenced by what others were doing ... so it didn't matter what other bands were doing ... we did what we were doing.

I think it was that we were really seasoned musicians. We had serious roots that spanned different cultures, obviously the blues.

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 so much that can be done on the guitar. And that's what is so good about the guitar - everyone can really enjoy themselves on it and have a good time, which is what it's all about.

I do not worship the devil. But magic does intrigue me. Magic of all kinds. I bought Crowley's house to go up and write in. The thing is, I just never get up that way. Friends live there now.
