This is a fantastic set of great piano playing. I would say personally, that it ranks among the best. Very refined, insightful, on the other hand not heavy, just original, somehow as for the access to the played works it is in its own class. Not in the superiority of playing, no, Nat is great, but there are for sure other great players as well. But he is unique in his concept. I cannot describe it, but if you want to hear e.g. Beethoven as never before and after, go for Nat. Do not worry, it is not unnatural, superartificial, original for the reason to be original. No. Nat is genius taking in the Beethoven scores and ideas and giving it out in absolutely beautiful and special manner. The same for Schumann, Brahms etc. Believe me, I heard many Beethovens and I like very much Richter, Gilels, Arrau, Backhaus, Haskil, Annie Fischer, also Barenboim, Serkin, Kempff, Chodos, Michelangeli (in his few Beethoven pieces), Horszowski, Sofronitsky, Yudina, BUT Nat belongs there too and with very prominent place.
