I've read enough posts by 'rachmaninoff_forever' to know why he +1'ed the comment so surely the case is settled based on that alone?
If you do not think that life experience plays a part in performance, there is absolutely no need to continue this discussion since the whole concept of piano playing at the highest of levels is beyond your comprehension; offended or not, that is a simple fact of piano life.
Even Liszt's masterclasses had him discuss experience and true emotion and there were many peices that he would not accept to be played, no matter how good the student, since they were not mature enough to attempt it yet. Life experience plays a 99% role in playing excellent piano, 1% being techinicalities and fingerwork which would be so engrained in your body and soul that no technical feat is too great.
Have you read Cziffra's biography? The same is said by him; I am not trolling with nonsense here so do not assume as such.
It is indeed sad that his father died young, but this Chopin piece is not about death. You can't compare one tragic situation with every piece of music you ever play! He could play the Chopin Prelude in E minor (the one with just chords in the left hand) since that is heart-wrenching and was even subtitled by George Sand's daughter on the island of Manorca where he wrote it, and others, as 'suffocation', along with feelings of despair. Now if he played that whilst thinking of his last days with his dad, it would perhaps be one of the most wonderful performances ever!
There you are 'telling' us that your video is incomparably the greatest version of this piece, but based on what? On your own interpretation. Yet, there you are simultaneously telling us that our opinions are wrong. I don't get it?
It's a great performance; all the videos are of this, but even without knowing anything about his age, I'd still say it was fast and the dynamics/general control of the piece's movement do not move me in the same way as the others.
You could just as well post a video of some 6 year old child 'prodigy' (the most vulgar term in the English language) playing Beethoven and say it's the great piece. I would then say that the kid doesn't even know what year Beethoven was born, how many other pieces he wrote, that he was probably half deaf when he wrote that particular piece or the background to the piece, if indeed it has somethin of interest.
Then show Cziffra playing it who was indeed a child prodigy, but then went on to be invovled in war, escape, be captured again, his hands tortured, his son die in a house fire, and then hear that piece. His absolute, unimaginable control of his hands despite torture (he wore a wrist band on his right arm to give more strength following torture) and his complete awareness and appreciation of Beethoven and his life.
But I suppose the child prodigy plays it better in your eyes...
