I don't think that is a high school. I think the are MT students at the Shenandoah Conservatory, based of what is posted on the video... that's unfortunate.

Yep, that's a mess, and yep, they're from Shenandoah University. When I first saw this video a couple weeks ago, I just about threw up. According to a couple of my friends who go to SU, one for MT, they say that these kids are extremely into themselves. It's a pity that they can't see how terrible their performance is.
