You can't overthink the music. Mood and intensity can't be manufactured. The blues isn't about structure; it's what you bring to it. The spontaneity of capturing a specific moment is what drives it.

Led Zeppelin didn't get that kind of Beatles screaming. We had a more sort of macho crowd. But I remember once in the early days of The Yardbirds, we were playing on an ice rink, and the stage was mobbed by screaming girls. I had my clothes torn off me. That's a really uncomfortable experience, let me tell you.

From the classical guitar right through to the furthest electrical experiments and everything in-between, it's amazing what the guitar can actually do. I mean, when one thinks about sounds.

I will still carry on changing all the time.

I bet you can't play slide piano.

Just because you play bass, doesn't mean you have no presence.

I don't want to get too dippy about all this. If you take the view of the scientist and everything is in a state of vibration, then every note is a vibration, which has a certain frequency, and you know that if you put 40 beats into a frequency it's going to be the same note every time. You take that into infrasound and people can be made to be sick, actually killed. Taking it the other way, not to be too depressing, what about euphoria, etc., and what about consciousness being totally... no, I won't go into that one. Time warps.
