(Retraction: A reader has confirmed my wrongness. It was Jayce Ogren with a shaved head.)
My boyfriend and I went to a free LA Phil concert at Disney Hall and we got a real treat, Gustavo Dudamel was conducting! (Or someone who looked alot like him with a shaved head.) How very generous of him. Jayce Ogren was scheduled to conduct and from where I was sitting it looked like Gustavo. Gustavo conducting at that event would be like Brad Pitt introducing one his movies at the Arclight on a random Tuesday matinee.
