der is at leazt 2 wayz to play this piece:
a) One can play it in an objective, understated way, in order not to offend the creampuffs on grandma's tea table. I have not seen any evidence that the composer had this in mind.
b) One can construct a fitting paen to the composer's genius by summoning forth as much sonic fury as possible, with such brain-melting terminal prejudice that every living being within ten miles of the piano ends up spattered in gore and in need of psychiatric help.
Maybe the recording on the link defines a new way of playing it.
I can't judge this because the link is broken.
