Music can always be a life-changing experience, for musicians and fans, or at least life-affecting, but it depends on to what degree.

I suggested back in 1980 to do a chronological live album, but there wasn't that much enthusiasm for it.

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

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.

There's a very old recording maxim that goes, 'Distance makes depth.' I've used that a hell of a lot-whether it's tracking guitars or the whole band. People are used to close-miking amps, but I'd have a mic out around the back, as well, and then balance the two. Also, you shouldn't have to use EQ in the studio if the instruments sound right. You should be able to get the right tones simply with the science of microphone placement.

Many people in the neighborhood liked hip-hop and house music, and I couldn't play that. You can't perform that on guitar or drums, which was what I was playing, at the time. But, I got so much from mariachi bands that were constantly playing in the neighborhood.

I love playing. If it was down to just that, it would be utopia.
