I hesitate and decide not to call what this link pointed to piano playing or interpretation only...
Piano interpretation is a relative perspective on some score, more or less with the infused spirit of the composer...Piano interpretation can be teach, it is more or less right or wrong like all that can be learned in a relative way...Piano interpretation is relative like all interpretation... And it suit a taste...
But this piece of piano, if you listen to, communicate so much energy, so much moving spirit, that it is no more piano lesson well done... If it is something, it can be repulsive for some who are not prepared and too much refine now to be transformed; it is not refine perfect playing, it is not even right nor wrong, it is beyond which anybody can decide or choose to play... It is literaly a case of possession, like in demonic possession, an hypnotic attempt, or agression, a transcendental moment, that you can listen to thousand times, and after each listening, the emotion is trivialized in the background of past experiences and will never be...At the end you can verify with some comparison with any other pianist among the best playing, they can be more "perfect", more mathematically accurate, more respectful of the score or of the composer intent, more "humble" or so it may seems at first, but they will never be and are not a volcanic eruption in the heart, nor a tectonic displacement of some waves in the brain...
I dont think this pianist is a pianist among others...This is a magician...A dangerous one perhaps, like Liszt was, or Scriabin was after testimonies of all their contemporary... One thing is sure, this interpretation of " la vallée d'Obermann" de Liszt, suggest to me the revelation that it is finally impossible to learn this way of playing piano, or possible only to a certain extent, like it is impossible to learn numbers the way Ramanujan did ( the great G.H. Hardy think that about Ramanujan praising him greater than even Hilbert, and for example Grothendieck in contemporary mathematics is in the same mythological category)...In the same way, one does not decide to learn to become Buddha or Christ, excepted deluded ones...Or for example nobody except fools decide to save humanity against itself, like Scriabin think he will do with music and this without being a fool himself... If you compare for example Stravinsky, a pure productive perfect genius, with Scriabin this imperfect god, you will discover the same abyss separating mortals, even great, of immortals even small one...One chord of Scriabin sometimes equal the works of others...
Men plays, gods create...
