The head moving I can understand. Seems it's common with woodwinds (and violins "swaying" to and fro). The vibrato is done with the embouchure, I believe. The hands over the ears thing, however, is just weird.

Sad but true, most of the time I can't begin to complain about any orchestral players that I am around, cause they are so much better than I am....
