It's interesting when something new comes along, a band of dwarfs playing electronic harps or something, but I'm not searching.

The key to Zeppelin's longevity has been change.

There was no working title for the album. The record-jacket designer said `When I think of the group, I always think of power and force. There's a definite presence there.' That was it. He wanted to call it `Obelisk'. To me, it was more important what was behind the obelisk. The cover is very tongue-in-cheek, to be quite honest. Sort of a joke on 2001. I think it's quite amusing.

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

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

You can't expect to be the same person you were three years ago. Some people expect you to be and can't come to terms with the fact that if a year has elapsed between LPs, that means one year's worth of changes. The material consequently is affected by that, the lyrics are affected by that... the music too.
