The term "genius" gets used far too loosely in rock & roll.

(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.

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

My vocation is more in composition really than anything else - building up harmonies using the guitar, orchestrating the guitar like an army, a guitar army.

The idea of a hypnotic riff as the prime mover of a piece of music has been around for a long time, whether you're talking about the Delta blues or music from Middle Eastern and African cultures.

I really wasn't needed... Just straightening up riffs, that's all. Just two guitarists doing it instead of one.

Well, Led Zeppelin IV! That's it really. I'll tell you why the album had no title - because we were so fed up with the reactions to the third album, that people couldn't understand why that record wasn't a direct continuation of the second album. And then people said we were a hype and all, which was the furthest thing from what we were. So we just said, `let's put out an album with no title at all!' That way, either people like it or they don't... but we still got bad reviews!
