A musical promoting gay marriage? Hmm. I don't think we could ever perform this at our school... I mean, if they wrote angry letters about The Marriage of Bette and Boo then this would never go over well. *snicker snicker*
Youtube is doing this project where they've commissioned Tan Dun to write a symphony for the first internet collaborative symphony orchestra. What you do is you record your instrument part to a video of Tan Dun conducting the piece, submit it to youtube, and record something in public domain (there are suggestions on each instrument page) and then somehow they pick the members of the orchestra. They're performing in Carnegie Hall in April. I think it's a pretty cool idea.
Here's the London Symphony Orchestra performing the piece.
