It's unlikely that any of the Internet dwellers I know has managed to miss "OK Go," but just in case:
So now that you know the band here's why I bring them up. They're fairly well-known for their imaginative do-it-yourself approach to producing their music videos. They (presumably with assistance) contrived this epic Rube Goldberg contraption as the video for one of two versions of their new song "This Too Shall Pass:"
The second version, also pretty groovy, utilizes the Notre Dame marching band and a somehow non-annoying children's choir to produce a pretty epic sound at the song's crescendo.
