2;05-4:36 Now this is where it gets really weird, The second and more famous piece by Alvin Lucier – I am Sitting in a Room. The dialogue explains the experiment;
I am sitting in a room different from the one you are in now. I am recording the sound of my speaking voice and I am going to play it back into the room again and again until the resonant frequencies of the room reinforce themselves so that any semblance of my speech, with perhaps the exception of rhythm, is destroyed. What you will hear, then, are the natural resonant frequencies of the room articulated by speech. I regard this activity not so much as a demonstration of a physical fact, but more as a way to smooth out any irregularities my speech might have.

Skip through the 45 mins in 10 min jumps and you will hear the deterioration of his voice and the resonance of the room starting to dominate as it returns to an equilibrium, but never completely, and that was my point, an interaction always leaves a resonance, an effect or a distortion like the butterfly wing of the chaos theory of weather.I tried to show this visually as the track played, pulling people into a dream like state.
By the end, there is still a remnant on the screen after the decay of division that will never to entirely disappear.
