I do really believe that all guitarists have a different character that comes through, that's a strong character, the stronger the person is.

The element of change has been the thing, really. We put out the first one, then the second... then a third LP totally different from them. It's the reason we were able to keep it together.

So far I've been very, very fortunate because it appears that people like to hear the music I like to play. What more fortunate position can a musician be in?

The idea of a hypnotic riff as the prime mover of a piece of music has been around for a long time, whether you're talking about the Delta blues or music from Middle Eastern and African cultures.

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

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.

Right from the first time we went to America in 1968, Led Zeppelin was a word-of-mouth thing. You can't really compare it to how it is today.
