When I have a creative block, I take walks. I like to see what shapes stick out - so many legs rushing by at once, it can seem abstract. I don't need to see great art to get stirred up. Music does that for me more easily.

My forms are not abstractions of things in the real world. They're also not symbols. I would say that my job is to invent these forms and to put them together in a way that keeps your interest, to give the forms a quirky identity so you can engage with them, so you realize there's an inner intelligence or logic. If you stop asking what they mean, or what they remind you of, and just look at them for 29 seconds, you find that they want to explain themselves and show you how much every tiniest detail is related to the whole.

I've been playing piano my whole life but I'd never tried to understand how compositions are made really. Try to imagine if you'd loved paintings your whole life but had never painted one. My aspiration now is just to understand. I don't have professional pretensions. I've learned so much. So many things I've been doing in the visual, two-dimensional painting world parallel many of the inner working of music - how intervals resolve into each other, harmonic rhythm, tonal things - there's a whole vocabulary that overlaps. Sometimes people see pianos in my works - that I never think.

I'm not such an artist type that I can't handle the real world. I read the financial pages, because most people don't talk about art.

If you come every day or every month to my studio, you won't see that much change, but if you come once a year, you'll see big new categories opened up.

I underwent a whole process of slowly letting go of idiosyncrasies and habits and embellishments and everything extraneous to the essentials that I'm unwilling to let go of. I never dreamed that I would be making black-and-white paintings with so little embellishment. But it's been liberating in many ways to let go of that and yet see what I did want to retain.

For me becoming a painter was an Everest, in terms of what I thought a painter was. There are many roads to becoming an artist. For me it wasn't art school. I didn't have that go to art school and then get a gallery. It's more like, how deep is your inner library to cull from. It's certainly not about technical prowess, just about depth of investigation. It takes time. I had 15 years of painting under my belt before my first New York show. I was glad to have that. It's a good thing to spend your twenties getting your craft.
