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.

If I ever really felt depressed, I would just start putting on all my old records that I played as a kid, because the whole thing that really lifted me then still lifted me during those other times. It was good medicine for me, and it still does that for me when I put something on. Isn't it wonderful that we've got all that good medicine? I think it's got to be all part of our DNA, this mass communication through music. That's what it is. It's got to be, hasn't it? Music is the one thing that has been consistently there for me. It hasn't let me down.

There's so many different styles and facets of the 360-degree musical sphere to listen to. From tribal to classical music, it's all there. If the bottom was to sag out of that, for God's sake, help us all.

Live Aid did feel like one hour's rehearsal after several years, but to be part of Live Aid was wonderful. It reall was.

I'm still searching for an angel with a broken wing. It's not very easy to find them these days.

All my houses are isolated. Many is the time I just stay home alone.

You absorb so much from whatever your environment is, as an artist, and you learn to take from it what can help you create.
