Alvin Lucier - Silver Street Car
The performance consists of moving the geographical locations of these two activities and changing the speed and loudness of the tapping. During the course of the performance, the acoustic characteristics of the folded metal bar are revealed. Using one hand to dampen the triangle with the thumb and forefinger, the player taps the instrument with the other.
The title of the work was taken from the Surrealist text, Instrumentation (1922), by Luis Bunuel.
