I put the word 'modern' in scare quotes to indicate that this is a recording on the piano that does not, however, like Feltsman, romanticize the music. What some (on the American Amazon site) may consider boring, straightforward, clinical etc. I consider to be honoring Bach's intention. Bach was writing before the onset of romantic era taffy-pulling of phrasing and his music really ought to be played that way. This is not to say that Aimard isn't a master of phrasing and certainly his ability to bring out various contrapuntal strands is virtually unmatched. As for technique and musicianship, there are few pianists playing today who are in the same league as Aimard. That's probably the reason he can, once he sets his mind to it, play such disparate music as Messiaen's 'Vingt Regards' and Bach's 'Art of Fugue' as stunningly as he does.
If you are wanting a piano version of 'Art of Fugue' and, much as I love Sokolov's version (available, in any event, only in a multi-disc set), if you only want one version this is the one to have.
