As much as I generally don't like to just favour individual pianists... To me - Pollini is the piano god.
I have heard a great number of his recordings from different composers and not only do they seem to be technically flawless, but they also still retain energy without drastically speeding up the piece to do so.
Look at Lang Lang - SEVERAL of his performances are seen as impressive, ONLY because they are played incredibly fast, however I feel that because of the speed - they sacrifice melody and lyricism.
To me sadly enough, Richter is good, but I feel that the video may be sped up slightly only because of two reasons... Very early video recordings were sometimes a little fast when played back, so I personally think he probably played it in real life a fraction slower than he did in the video - I also say that because the piece is about a semitone higher than it should be.
So I can see what you mean about:
I would just attack the whole thing in one go and think about someone I hate. I think this piece is about the bombardment of Warsaw, its anger really.
However, if you're talking about the Bombing of Warsaw in WWII, then we're talking about an event that happened almost a century after Chopin died, so I can't convince myself to think about that when playing this piece. Richters performance did seem to have a lot of hate running through it, but Koziak seemed to also lengthen some moments to allow the melody to breathe a little - much the same as Pollini.
Anyway, I'm still working on the piece and I still have 3 weeks to perfect it. Here's hoping.
