Let me explain something about guitar playing. Everyone's got their own character, and that's the thing that's amazed me about guitar playing since the day I first picked it up. Everyone's approach to what can come out of six strings is different from another person, but it's all valid.

I'm just looking for an angel with a broken wing.

I can tell how far I ought to be going, I know how to get there, all I've got to do is keep playing.

The key to Zeppelin's longevity has been change.

I like change and I like contrast.

I know where I'm going musically. I can see my pattern and I'm going much slower than I thought I'd be going.

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.
