...or "Butt Music From Hell"?
Either title is appropriate, as Tumblr user Chaoscontrolled123 has discovered and transcribed some music found on the backside of one of Bosch's unfortunate residents of hell.
I'm thinking that between this and the hidden music in The Last Supper, a concept album of music hidden in great art might be in order. Someone just needs to discover about 8 more tracks. Otherwise we just have a single and B side. Oh! B side. See what I did there? Didn't even mean it.
