I have to agree with the other reviewers who express reservations about Grimaud's getting to the bottom of this music, despite all the rubato, all the thrashing at the keyboard. Rather than enhancing this music, I heard all the Big Romanticism as an indication that she really doesn't know how to make these works sing on their own. Right after playing this disc I put on Julius Katchen in these same works and was amazed at the effortless, direct quality of his playing. These are really very simple pieces in the way they strike the ear. Of course, they're really not simple (certainly not techniclaly) but they are supposed to sound simple and direct. I think Grimaud miscalculates the weight each of these miniatures can bear and makes them too heavy, too overburdened. It's like playing the Brahms Second Concerto as though it were the Brahms First Concerto.
This is the second time she has recorded at least some of these works. Her earlier go at op. 118, for Denon, despite already showing a tendency towards the outsizedness here, are cleaner, clearer and more expressive. Here, as in a number of her recent recordings, I feel like she's hiding behind her keyboard technique rather than using it to illuminate. Maybe she needs to spend less time with her wolves.
