This track was created by playing a segment of steel rail found along the U.S./Mexico border in Sasabe, Arizona with a cello bow and implements of mass percussion.

The segment appears to have begun life as a train rail roughly 100 years ago. At some point it was shipped to the border where it was welded into a barricade to slow human and vehicle traffic.

The found segment seems to have been created when the barricade was dismantled to make way for a roughly $57 million wall of steel columns.
