Letter from Niki de St. Phalle to Pontus Hulten: “In 1961 I shot at canvases because shooting allowed me to express the aggression that I felt. An assassination without a victim. I shot because I liked seeing the canvas bleed and die. I shot to reach that magical instant, that ecstasy. It was a moment of truth, I trembled with passion when I shot at my paintings”. Four tracks from 2010 by Pierre Henry in memory of Arman composed for the recent retrospective at the Pompidou.
