First there's this that Richard James posted where he reversed the midi
score for Avril 14th, and played it back on a Disklavier.

Then I started playing with it in VCVRack, using the 'Confusing Simpler' by
Nysthi. This will load a sample and let you playback slices of it. Add
some effects and it turns into a haunted dancehall.
