Yo Yo Ma was brilliant as usual. His effortless and flawless playing was superb. He could have varied the music some, since all Bach program became tedious. Also I have never been to a concert where a standing ovation was given during the performance. I thought this was odd. Also I was surprised that drinks were allowed in the concert hall. I have been to many classical events and one drank in the lobby during intermission. Even though it was announced not to take photos, many patrons were doing this. Ushers should be more vigilant.
