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. ... I always felt if we were going in to do an album, there should already be a lot of structure already made up so we could get on with that and see what else happened. ... I always believed in the music we did and that's why it was uncompromising. ... I don't think the critics could understand what we were doing.

If you wanted to chart new territories and head off over the horizon, you had to make sure you weren't overly influenced by what others were doing ... so it didn't matter what other bands were doing ... we did what we were doing.

I'm at my best when I'm exhausted and under pressure.

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!

(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.

My guitar style was developed during that 10-year period. That's me. That's the way I play, and I don't wish to play any other way. Our own individual identities are firmly stamped on this album.

So many people are frightened to take a chance in life and there's so many chances you have to take.
