Occurred on December 20, 2019 / Oak Grove, Minnesota, USA
Info from Licensor: This is at my home out in the detached shop Friday evening Dec 20th, 2019. I was working on a snowmobile and dropped 2 wrenches together accidentally and it made a perfect 3rd chord. I then poured out all 60 of my wrenches and spent 10 minutes finding the right tones.
