I listened to her Chopin also. She has a very strange way of observing the Chopin rubato - you can tell that it's important to her to stay more or less in tempo, but she has wild surges, both in tempo and in dynamics.
After I read your response, I listened to her some Chopin, too. (Before that I hadn't.) I don't like her Chopin... Her emotion is too much, quite unrestrained. I think that leads to that strange rubato. It is a pity that I cannot find that subtle and refined way from that Scarlatti there.
Anyway I listened to that Scarlatti a lot of time and got never bored. I just love that performance! I found her La Valse (Ravel), too and my jaw dropped. I never saw such a crazy power and technique. I don't know Rach well, but her Rach sounds much better than her Chopin. More subtle, more natural, more colorful. I read somewhere her next program is Bach's WTC. (The current or last one was whole cycles of Rach's Etudes-Tableaux and Chopin's Etudes on a single evening. I'm wondering how the young and thin girls like her or Alice Sara Ott (who played all the Etudes d'execition transcendante plus Waldstein sonata in a recital) have the stamina to play such a big program
