You don't find geniuses in street musicians, but that doesn't mean to say you can't be really good.

Sometimes, I must admit, I'd like to have a second guitarist onstage with me, but it wouldn't look right. I'd like to play for another 20 years, but I don't know... I just can't see it happening. I don't know why. It's a certain foreboding... a funny feeling... vultures.

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.

I had another idea of getting a traveling medicine wagon with a dropdown side and traveling around England. That might sound crazy to you, but over there it's so rural you can do it. Just drop down the side and play through big battery amps and mixers and it can all be as temporary or as permanent as I want it to be.

There's too many good musicians around for the music around for the business to be sagging.

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.

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