Bizarre (or should I say unique?) recordings

[perprocrastinate]

Aside from Glenn Gould's singing/humming/mumbling.

Cziffra, Liszt Transcendental Etude No. 10 (a lot more legato than most recordings I've heard)

Cziffra, Liszt Transcendental Etude No. 4 (2-4 fingering)

Cziffra, Chopin Etude 10/4 (I can't quite put this one in words)

Cziffra, Chopin Etude 25/12 (that boom in the bass, I have no idea how it sounds like that)

--
Lol, they're all Cziffra.

Pogorellich play what is allegedly the Tschaikovsky 1st Piano Concerto:

Emerson, Lake, and Palmer, Moussorgsky's Pictures At An Exhibition. Was very disappointing.  I play better than those guys even without the synthesizer colors.   
I love the Fritz Reiner Chicago Orchestra version even though it is an obsolete monaural LP.

A recording of the Beethoven 5, with a war going on outside! If you listen closely you can even hear the canons outside!

I second on Pogorelich. Check out his Chopin Preludes; completely different from the rest of the lot.
