Alvin Lucier "I Am Sitting in a Room" 1969

I am sitting in a room (1969) is one of composer Alvin Lucier's best known works, featuring Lucier recording himself narrating a text, and then playing the recording back into the room, re-recording it. The new recording is then played back and re-recorded, and this process is repeated.
