According to the product information, you're not supposed to use the Korg CM100L contact mic for anything besides clipping onto an instrument and plugging into a tuner, but sound sculptor Glenn Weyant doesn't care much for instruction manuals. After all, there is no instruction manual on how to record the sounds of a wall or a statue or the desert wind, but he did it anyway for his SonicAnta project, a sound project that focused on the sounds of the border wall in Nogales, AZ that marks the separation between the U.S. and Mexico.

Glenn talks about using the CM100L outside of its intended purposes for the recording of this project, which features ten hours of sound compressed and layered into a single hour, just like Death Magnetic, except more listenable.
