During fall semester of 2010, I began taking students on five-day field trips to the Arizona–Mexico
border. One part of these trips involves meeting with sound sculptor Glenn Weyant, who plays the border
wall as a musical instrument. Weyant attaches contact microphones to the wall and plays it, sometimes
bowing the steel structure with a cello bow, and other times playing it rhythmically with what he calls
“instruments of mass percussion.
