I've already posted this in The Old Forum, but wanted to do something fun (see below) so I'm reposting it here.

MP3 audio (rendered on a Kawai piano soundfont)
And here's the fun thing:
Exuberance in reverse audio, rendered on an el cheapo reed organ patch I found online and reversed with an audio processor.
I chose reed organ because of its near-constant note envelope, which works better in reverse than something with a lot of decay like a piano.
The reason for reversing is because this particular fugue revolves around the inversions, retrogrades, and inverse retrogrades of the subject and countersubject. Reversing the audio "undoes" the retrogradation, and since the very last entry at the end is the subject in retrograde, you should be able to immediately identify the subject at the beginning of the reverse audio. The other entries will also be similarly remapped, so you might be able to recognize some of them.
Now, I don't know of any audio processor that inverts pitch, but if there is one, we'd be able to "undo" both the retrograde and inversion, and you'd be able to identify exactly which entry is the retrograde inverse by listening for the (counter)subject in the result.

The original breakneck-speed 115 bpm had more of that energetic, unstoppably-barging-forward feeling that I had in mind, but yeah, it does make it difficult to follow the lines. Originally I was considering to write the tempo marking as "as fast as you can go while still making the 32nd notes sound clearly".
