Straight No Chaser goes viral

Watch the video above and admit that I'm right: a cappella music is it. Just listen to the perfect harmonies of Straight No Chaser, an all-male a cappella group that got it's start at Indiana University in 1996. Fast forward a decade(+), factor in the endless possibilities of the internet, and success! This group has gone viral. Better yet, they're currently on a national tour. Tickets please!
