You can see the roughness of structure and the spots like wounds from battles on the canvas. The tops of skyscrapers with windows like eyes constantly remind you that there are laws surrounding the wastelands, and so you hide in the deep grass when you make love to a girl in dirty clothes, and experience how your nerves of seeing become stronger and stronger and every little sound more and more intense. That's what Pasolini's poetry is partly about; he was a street guy and therefore I avoided beautiful new wood or metal for his sculpture... The wasteland was Pasolini's other side; the boys, the knives, the nights, the tensions.
