Two years ago I saw this young soprano in Il Trovatore. I thought she was nice, promising, fresh-faced, but still a work in progress. What a joy it was then to see her last night in Cosi fan tutte -- she absolutely lit up the stage. She was exactly the right mix of immature, vain, but adorable as Fiordiligi. Her voice is exactly what Mozart sopranos are supposed to sound like -- creamy and silvery, and her singing has such cleanness. My review of the complete performance is at parterre box.
