Thank you so much for your thoughtful observations!!!!! I explained it a little in my post to essie.... he really is a great violinist and has potential to be a great violist, but to try to realize that under extreme pressure with so little preparation time *could* be bad. B said he was sure they'd understand "i'm too busy excuse" and in this case it was actually true... it was just such an amazing opportunity that he was thinking about backing out of his other job(s) in order to do it.
