"Inopportune: Stage Two," detail (2004)

"There’s a lot of talk about the content of my work, about the subject matter or the historical background. But there’s not a real in-depth investigation into the visual impact. It’s through visual impact that you transmit these ideas. And it’s through visual impact that this pain is felt, and you can actually elicit a very direct response from the audience, a very strong response. But it’s the treatment of all the elements that has the power to do this."
