I can't take credit for finding this on my own; it comes from The Daily Swarm, who found it on a Louisville hardcore blog. It's a band called Confide. They're covering The Postal Service's gentle electro-ballad "Such Great Heights." I guess it's a testament to the song that it "works" both in this incarnation and the way that Iron & Wine did it a while back. Check 'em both out. If you play both videos at once, Satan will tell you to kill something.
