“Amelia… was recently looking at the famous triptych painting The Garden of Earthly Delights by Hieronymus Bosch with a friend when they noticed a man on the right-hand panel with musical notes written on his butt. Highly amused, Amelia then transcribed these notes into modern notation and created a little sound clip that has been colloquially called “The Butt Song From Hell” — which is available for listen on her Tumblr.”
