LUCIER, ALVIN: I am Sitting in a Room
The classic recording for voice and tape that set a whole movement in train. For 45 minutes Alvin's original recording, which describes the process he is undertaking, changes from coherence to pure noise as it follows the process: first it is played back into the room in which it was recorded, then that playback is recorded in the same room and in its turn played back - and so on until all that remains is an unintelligible, inhuman sound that bears the print of the acoustics of the room itself. A landmark work. Indispensible.
