“I was seated on a platform suspended 14 feet above the floor. My hair was braided and my face was covered with red body paint. Four 500 watt movie lights were placed around me facing the front entrance of the space. My voice was amplified by three speakers. As people entered the gallery, I repeatedly yelled at them get the fuck out, get out immediately. Because the sound was very loud and contained high frequency feedback, most people left quickly.” —Chris Burden, Shout Piece (1971)
