the video is amazing, but sorry just giving my opinion. When you've studied music as much as me these videos just aren't that great to me. I'm no Heifetz but I did have university professors as teachers when I was a kid and also continued into college. My son started playing violin concerti when he was 8 (Bruch, Mendelssohn, Tchaikovzky). Like I said, it's ok from a cute perspective, it's just not my thing, but that doesn't mean others don't like it.
