I'm not really an opera fan, but this guy has a really magnificent voice. The judges were amazed, the audience went nuts. It's really short -- go listen. :D
He made it, too -- he's singing opera now and looks very fine in a tux. His web site is here.
I've never actually watched this show, or American Idol or any of the other talent searches, but if this is what comes out of them, even just occasionally, then they're definitely not a waste of bandwidth. Follow the links and watch someone's life change.
