There's music that can affect people in their lives, and they will always relate to the point that they heard it and experienced it, either if you're playing it or you're receptive, as an audience.

There's so many different styles and facets of the 360-degree musical sphere to listen to. From tribal to classical music, it's all there. If the bottom was to sag out of that, for God's sake, help us all.

Every musician wants to do something which will hold up for a long time, and I guess we did it with 'Stairway to Heaven.'

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 can only listen to what I'm working on, at the time. I can't listen to anything else because I don't want to copy it.

You don't find geniuses in street musicians, but that doesn't mean to say you can't be really good.

I may not believe in myself, but I believe in what I'm doing.
