Artists say that paintings are never done. I sort of feel the same way about music. I would never say something is perfect. There are performances that can generate a lot of emotion in me when I hear them, but I can't say if anything is perfect.

The guitar to me, from the classical/gut-string guitar right through to Hendrix, et cetera, has all the range [of sound]. Within those six strings it is incredible what one can get sound-wise. It's just down to imagination, really.

I guess the solo from 'Achilles Last Stand' is in the same tradition as the solo from 'Stairway to Heaven'...it is on that level to me.

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.

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.

The way I see it, rock & roll is folk music. Street music. It isn't taught in school. It has to be picked up.

You absorb so much from whatever your environment is, as an artist, and you learn to take from it what can help you create.
