If you're criticized then you can use it as an experience. Compliments, you can't use.

I relate to happiness as an ecstatic moment - something you don't create, you encounter.

When I was four years old, my mother put me into a school for early music education where you get perfect pitch and harmony and composition.

Fracking kills, and it doesn't just kill us. It kills the land, nature and, eventually, the whole world.

If everybody thinks of something, then it will happen. Your mind is part of the universe. It is connected, you can use its energy.

What all of us artists are doing is using our pain as material to create our work.

I always believed that my work should be unfinished in the sense that I encourage people to add their creativity to it, either conceptually or physically. Back in the 1960s, I was calling for 'Unfinished Music,' number one, and number two, with my artwork - I was taking unfinished work into the gallery. And that's how I was looking at it.
