I watched it last night and it was good. There were some times during the first 2 songs/acts, whatever the split was in the presentation, where I thought "good but still has some room to grow and improve".
But.....that 3rd piece was simply amazing and I absolutely agree that she is and will be one of the masters of the art!
She has one of these characteristics that I see time and again with excellent musicians. It's almost like she is channeling something through her and into the music! The mannerisms, body language, and facial expressions while she is playing says just as much as the music does. Just a complete natural, like it's something that she is just the media to get it out!
