Needless to say that Arturo Benedetti Michelangeli was one of the most stunning pianists of all times. The sophistication of his playing, the complete lack of outward effects and sentimentality and his unmatched pianistic abilities are the stuff of legends.
His best time was from the 1940ies into the 1960ies, nearly everything from that time is at a truly stratospheric conceptual level of interpretation.
It is also fascinating to see the quality of his playing in shorter pieces, such as a 1.55 minute long Nr. 6 from Canciónes y Danzas by Federico Mompou ( only first part ) and Chopin’s Berceuse Opus 57.
