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.

We kept moving forward and didn't try to recreate the past .. the approach to each album was radically different every time. Many bands would have some success and, because they were locked into having a single - something we didn't have to worry about - they had to make sure there was something similar on the next album ... that was never the idea with Led Zeppelin .. the goal was to keep that spark of spontaneity at all times.

When you hear the melodic structures of what classical musicians put together and you compare it to that of a rock & roll record, there's a hell of a long way rock & roll has to go.

The blues appealed to me, but so did rock. The early rockabilly guitarists like Cliff Gallup and Scotty Moore were just as important to me as the blues guitarists.

(The Song Remains The Same) is not a great film, but there's no point in making excuses. It's just a reasonably honest statement of where we were at that particular time. It's very difficult for me to watch it now, but I'd like to see it in a year's time just to see how it stands up.
