An excellent performance. Is is no less than amazing that at his age and recent heart attack, that he can give such an energic performance. He held nothing back. Fantastic all the way to the end, and what an end!!! The orchestra was very complimentary to his music. Wasn't sure how that would sound, but it was great. It gave it great depth!. Overall - stunning performance!
