I believe every guitar player inherently has something unique about their playing. They just have to identify what makes them different and develop it.

The way I see it, rock & roll is folk music. Street music. It isn't taught in school. It has to be picked up.

I do really believe that all guitarists have a different character that comes through, that's a strong character, the stronger the person is.

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.

But if you want me to knock Kingdom Come, all I will say is that I heard the guitarist said he'd never heard my playing, and I'd defy any guitarist in American not to have heard Led Zeppelin.

If you're working at the factory and you're cursing every day that you get up, at all costs get out of it. You'll just make yourself ill.

The only term I won't accept is "genius."
