Sound made by bowing a detuned guitar tied to a clothes hanger. Recorded with two contact microphones. No effects were added, the apparent reverb tails are the waves resonating within both the guitar and the metallic clothes hanger.
Did this punching a shirt 4 times, and then rubbing the shirt with another 4 times. I found it great for torso and leg hits(first 4), and great for de-grappling moves and push aways(last 4).
