Hélène Grimaud - she's been around for a while now - has anyone else discovered her ?
Interview (video, 26mins ) in english after czeck intro. It includes impromptu passages from Ravel, Rachmaninov & Mozart. I have sometimes considered Mozart's work to be a bit mechanical, but this rendition proves otherwise; it's all in the nuance as Grimaud says - timing of milliseconds is what brings to life Mozart, and that of all composers.
Music however is not the only passion which motivates Grimaud. V surprising !
