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.

I guess the solo from 'Achilles Last Stand' is in the same tradition as the solo from 'Stairway to Heaven'...it is on that level to me.

So many people are frightened to take a chance in life and there's so many chances you have to take.

I know what I want to get down and I haven't got much time to do it in.

I'm not a guitarist as far as a technician goes, I just pick it up and play it. Technique doesn't come into it.

There will be a Led Zeppelin as long as there's a Jimmy Page, John Bonham, John Paul Jones and Robert Plant. This isn't a nostalgia band playing the hits forever. If anything ever happened and somebody left - which I really can't see happening - I don't think we'd bother to carry on. The magic for me is as it is now.

I like change and I like contrast.
