The element of change has been the thing, really. We put out the first one, then the second... then a third LP totally different from them. It's the reason we were able to keep it together.

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.

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

I love playing. If it was down to just that, it would be utopia.

Let me explain something about guitar playing. Everyone's got their own character, and that's the thing that's amazed me about guitar playing since the day I first picked it up. Everyone's approach to what can come out of six strings is different from another person, but it's all valid.

Every record is a portrait of the band at that time.

Right from the first time we went to America in 1968, Led Zeppelin was a word-of-mouth thing. You can't really compare it to how it is today.
