I was most blown away, however, by this little girl. Emma Resmini, 10 year old flute prodigy. Amazing. She played more beautifully and more maturely than almost any flute player I have ever heard, and she is only 10. She started playing flute when she was just 3 (!). I also got to meet her and her mother backstage after the concert and she is a sweetie.
