I know and admire this pianist for his albums of Debussy and Ravel piano pieces, he is my reference player when it comes to these composers. That he also plays Gershwin, was new to me, I think.
Its easy to play/interpret Gershwin wrong, too slow or too fast, too sober or too passionate, some players seem to just loosely bas eon him btu playing their own composition.
He plays he perfectly correct. Like he does with Debussy and Ravel as well.
