It’s a funny contradiction because when we started playing instruments as kids, the thing we didn’t want to do was jam. We wanted to have an idea. We wanted structure. Jamming was like this way of sharing the spotlight, where everyone got their own solo, every individual got their own moment to shine. When we were growing up, that’s how we thought of it. Eventually we embraced this more freeform approach. I wouldn’t call it jamming, but maybe it’s more about exploring.

It’s completely spatial. I follow Graham on that a lot. I really think that painting is about space and proportions and where things go; it’s what painting is. Form, if it isn’t the right color, it is not in the right place. And you know you can actually change the relationships a lot by changing the color a little. Yesterday, something happened in my studio. I realized that new things come to you all the time when you work in art. I had forgotten that if Graham wanted to make something slightly off-white, he used violet instead of greying it, and it’s really good. So, last night I remembered that, and the painting worked out.

For every painting, I first use the one-quarter inch masking tape to create the grid, dividing the surface across equally. There are four stages of taping. It begins with taping one layer on the whole canvas vertically, then proceeds the same horizontally. The next thing is to apply the selected color with a small brush, then remove the tape. Repeat this same process on the unpainted squares one more time vertically, then horizontally, then apply the last layer of colors. What I love is the degrees of surprise every time; to take each layer of tape off the canvas is to reveal new worlds of optical symphony.

I remember being present when a Jesuit priest in Rome asked Tennessee Williams, “How do you write a play?” and Tennessee said, “Well, I start with a sentence.” Well, I start with a sentence, and that’s how you write a book.
