Actually I did stumble across it on my "weird music instruments" rabbithole last night! They also figured out how to somehow play TVs and a space heater as guitars?? https://youtu.be/A0VYsiMtrNE?si=8SUpClphR2f1hBFf
The sound of that piece reminds me a lot of Emerson, Lake and Palmer's rendition of 'Fanfare for the Common Man'[1]. Progressive as Progressive Rock is though, I'm not sure ELP would have been let into the Toronto Olympics stadium with an assortment of electric fans and televisions!
