I can tell you exactly and this is a really good lesson that I had to learn. The song gets sent in some format or another, and I add to it what I think is mine to add to flesh out what was being sent. At a certain point what I’ve noticed is if I get into this space where I think “Oh and I need to add this and then I need to add that,” which is not really coming from the song, but from my own ego. I don’t mean that in a negative way, but just it’s just coming from me, it’s not the impulse of the music itself, then inevitably it starts sounding terrible to my ears. I’ve lost a couple pieces because of that. My motto is to try to stay very sensitive to when the piece is expressing what it came to express, and that I have augmented to make sure that it can be understood, but that I haven’t taken it off some place that it had no intention of going.

For me, especially with this last book, I had nothing else to say about these characters from this point in their lives. I felt like I’d reached the end of what they’re telling me—it wasn’t even what they’re telling the story, it’s more what versions of them I needed at that time.

Sometimes some of the things I’ve been working on for years and years, they’re just not getting any better or not going anywhere, so they fade away. And sometimes you start something, and within a few days, it develops enough that it feels complete. Each piece is different and develops itself in a different way. Some artists make the same thing for 50 years, and that doesn’t interest me. My current show at Lisson Gallery will be my 18 th with this gallery, I’ve been working with them since 1974, and all the shows have been different. You don’t repeat a show. So this solo show is comprised of pieces I’ve made in the last three years.

Well, I feel it. If I don’t feel it just the way I want it, then I’d rather destroy it than to keep it.
