Sometimes we need to tell ourselves that we're not going to do certain things, just in order to stay sane.

My booking agent, of course, here and overseas, their tendency is to want to build on a certain kind of measurable success, and I was thinking yesterday, what I'd like to do is maybe start to compile a list of the best 200 to 500 capacity rooms around the world and just start going to them again and again and again.

You're making something that won't be what it is until some unknown date in the future. All aspects of the personal disappear.

I had a lot of time to myself, and I would listen to a lot of music, mostly music that I knew fairly well and had a relationship with. And I'd think, well, what is it that I've never been able to do that this person or people are able to do with this song? Why haven't I been able to do it, and what can they do that I wish I could do? And then I'd try to do that. I'd start each day getting into the songs, and I'd think about how I might get closer to this music that I love, but haven't been able to make before.

Listening to it, it just doesn't sound like me - that's a younger self that didn't know who he was or what he was doing. I can't identify with a nebulous cloud.

When you're listening to a recording, you're supposedly listening to some aspect of the past in the present as you travel slowly into the future, but you also know there's a very strong likelihood that the future of that recording, whether you made it or whether you're listening to a Led Zeppelin record, is going to continue probably far beyond where you are.
