In the category of "I can't believe I hadn't heard of this until now", I bring you the YouTube Symphony Orchestra. Since I'm a big believer in not creating work when it's already been done for you, here's the description from the site:
"Play your part in music history. Interested in joining the first-ever collaborative online orchestra? Professionals and amateur musicians of all ages, locations and instruments are welcome to audition for the YouTube Symphony Orchestra by submitting a video performance of a new piece written for the occasion by the renowned Chinese composer Tan Dun (Crouching Tiger, Hidden Dragon). We have tools to help you learn the music, rehearse with the conductor, and upload your part for the collaborative video. And how do you get to Carnegie Hall? Practice and upload. Send us your talent video performance from a list of recommended pieces. Finalists will be chosen by a judging panel and YouTube users to travel to New York in April 2009, to participate in the YouTube Symphony Orchestra summit, and play at Carnegie Hall under the direction of Michael Tilson Thomas.The deadline for all video submissions is January 28, 2009. "
I'm sorry, but that's just too friggin' cool. Had this come along when I was still in my clarinet days, I very well might've posted a video entry. As it is, I've been watching a few of the clarinet entries (a very few) and here's one that caught my eye. She starts off with a couple of orchestral excerpts, but watch at least until 3:40, which is when the video shifts to a performance of the Adagio movement of Mozart's Clarinet Concerto, complete with a string orchestra accompaniment and a big, fancy dress! I'm voting for this girl.
