Query: The purest interpretation of Beethoven's piano sonatas ...

Unlike many more famous interpreters such as Emil Gilels, Alfred Brendel, Rudolf Serkin ..., Yves Nat plays so naturally that the sound could even appear rough ... It is also to be said that the recordings were made in the fifties and it greatly contributes to the authenticity of the sound ...You should definitely listen to these discs if You happen to be a Beethoven fan : in fact, You might remain amazed while listening to the latest sonatas, especially the last one, as Nat plays them much faster than any other as far as I know ...It gives an impression of lightness and simplicity even if these pieces are far from being easy and I think that this interpreter deserves the title of most natural interpreter of Beethoven's piano sonatas !
