I’m disappointed I wasn’t able to go see this in person, but the YouTube video will have to suffice. The embedded video is Part 1 of the performance.

The YouTube Symphony Orchestra is an innovative collaboration of amateur and professional musicians, who auditioned to be in the orchestra, and renowned musicians such as Michael Tilson Thomas, Lang Lang, Gil Shaham, Yo-Yo Ma, Tan Dun, and Yuja Wang. The collaboration culminated in a concert at Carnegie Hall on April 15.

There is an early review by ConcertoNet here. Also, the NYTimes critic Anthony Tommasini didn’t like the performance because it was not substantive enough and too gimmicky, but he did credit the innovative idea.
