I like change and I like contrast.

We were never a band that did 96 takes of the same thing. I had heard of groups that were into that kind of excess around that time. They'd work on the same track for three or four days and then work on it some more, but that's clearly not the way to record an album. If the track isn't happening and it creates some sort of psychological barrier, even after an hour or two, then you should stop and do something else. Go out: go to the pub, or a restaurant or something. Or play another song.

I played guitar all my life, all the way through the Yardbirds, but I knew that for me this was going to be a guitar vehicle, because that's what I wanted it to be.

I deal in emotions. It's the harmonic side that's important. That's the side I expected to be much further along on than I am now. That just means to say that I've got to keep at it.

But if you want me to knock Kingdom Come, all I will say is that I heard the guitarist said he'd never heard my playing, and I'd defy any guitarist in American not to have heard Led Zeppelin.

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.

I like change and I like contrast.
