There are very few people I can call real, close friends. They're very, very precious to me.

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.

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

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 may not believe in myself, but I believe in what I'm doing.

I had another idea of getting a traveling medicine wagon with a dropdown side and traveling around England. That might sound crazy to you, but over there it's so rural you can do it. Just drop down the side and play through big battery amps and mixers and it can all be as temporary or as permanent as I want it to be.

My vocation is more in composition really than anything else-building up harmonies using the guitar, orchestrating the guitar like an army, a guitar army. ... I always felt if we were going in to do an album, there should already be a lot of structure already made up so we could get on with that and see what else happened. ... I always believed in the music we did and that's why it was uncompromising. ... I don't think the critics could understand what we were doing.
