"For us, the idea of having a work that has contradictions is very important—when, in affirming something, it includes itself and attacks itself. How can you put together all of these things that have nothing to do with each other? You use glue! Glue can be an idea, a word. You can use an ideological glue."
"’Black Rainbow’ is a work I’m preparing to do for Valencia, Spain. I was invited to see the site in March 2003, and three days prior to my departure the Madrid bombing happened. Valencia is very famous for its really crazy explosive fireworks shows that they put on every year. But being there in that atmosphere, with the bombing that had just happened, I was really thinking about what possibilities there still are for fireworks. And what came to mind was making a black fireworks show."
