… seemingly impossible music can be found today in a group of musicians who use MIDI files (which store musical notes and timings, not unlike player piano rolls) to create compositions that feature staggering numbers of notes. They’re calling this kind of music “black MIDI,” which basically means that when you look at the music in the form of standard notation, it looks like almost solid black:
Blackers take these MIDI files and run them through software such as Synesthesia, which is kind of an educational version of Guitar Hero for the piano, and bills itself as “piano for everyone.” It’s kind of brilliant to imagine a novice piano player looking for some online tutorials and stumbling across, say, this video of the song Bad Apple, which reportedly includes 8.49 million separate notes.

This reminds me, for some reason, of the old Amiga demo scene.
