I played it last year. It's a piece you're never entirely finished with, though. Sure, it takes time to memorize, but I found that there were a lot of things about it that were WAY more difficult. Relationships between tempos, bringing out the right dynamics, how much accelerandos/ritardantos one should do etc etc... The amount of information for such a short piece, page-wise, makes it necessary for you to study every single bar under a microscope, sort of...I'm about to record it next week actually, I could post my recording here - don't expect the most amazing performance though.
It's such an incredibly poweful unique piece where basically all of the material is taken from the opening bars, and if you're not totally inspired in performance it ends up sounding boring.
It's a pain to memorize, and randomly almost all performances of it I hear completely misinterpret the tempo marking.

You mean the opening tempo marking? You think it gets played too fast? One tends to rush in this piece, especially in the builup to the big climax around page 4-5, and in the sextuplet figure that occurs sometimes.
