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.

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.

The key to Zeppelin's longevity has been change.

There's such a wealth of arts and styles within the guitar... flamenco, jazz, rock, blues... you name it, it's there. In the early days my dream was to fuse all those styles. Now composing has become just as important.

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.

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.

I think it's time to travel, start gathering some real right-in-there experiences with street musicians around the world.
