I'm Sitting in a Room by Alvin Lucier
I'm Sitting in a Room by Alvin Lucier is a sound piece where the artist records himself reading a text, then repeatedly replays and re-records it in the same room. Over time, his speech dissolves, from intelligibility, leaving only the resonant frequencies of the space - the room itself becomes the music.
