At the PROPHETIC SOUND Arianna Ferarri will sit on the floor, legs wide open. Between her legs will be a radio transistor: its exciter will be placed on her body. All around the exciter, attached on her flesh, there will be contact microphones, that will pick up the vibrations coming from the exciter. The sound coming from the radio will be transferred to her flesh as a vibration and then as sound waves, to the speakers. The body is treated as a computer program using signal processing —there is an input signal, and the program, based on its state and changing states, processes the signal, producing an altered output.
