Many people think of me as just a riff guitarist, but I think of myself in broader terms. As a musician I think my greatest achievement has been to create unexpected melodies and harmonies within a rock and roll framework. And as a producer I would like to be remembered as someone who was able to sustain a band of unquestionable individual talent, and push it to the forefront during its working career. I think I really captured the best of our output, growth, change and maturity on tape - the multifaceted gem that is Led Zeppelin.

The term "genius" gets used far too loosely in rock & roll.

I can tell how far I ought to be going, I know how to get there, all I've got to do is keep playing.

I can communicate far better on a guitar than I can through my mouth.

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.

But to put out a greatest hits on one CD was totally impossible, I just couldn't do it. The best compromise was to put out two CDs - Early Days - which is what it is - and Latter Days.

I'm just looking for an angel with a broken wing.
