We kept moving forward and didn't try to recreate the past .. the approach to each album was radically different every time. Many bands would have some success and, because they were locked into having a single - something we didn't have to worry about - they had to make sure there was something similar on the next album ... that was never the idea with Led Zeppelin .. the goal was to keep that spark of spontaneity at all times.

I can listen to all different sorts of music. I don't really care about The Next Big Thing.

You can't overthink the music. Mood and intensity can't be manufactured. The blues isn't about structure; it's what you bring to it. The spontaneity of capturing a specific moment is what drives it.

If you are on to something creative, school can also inhibit you. The wrong teacher, man, can really mess you up.

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 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.

There's so much that can be done on the guitar. And that's what is so good about the guitar - everyone can really enjoy themselves on it and have a good time, which is what it's all about.
