Awesome

Excellent video, great performance

goosebumps! 

I wish I had learned about it before it happened, the Westbahnhof is only 10 minutes away from my workplace. So I can just watch the video like everybody else.

Pure wonderment

Apparently not the first (or second or third) one.  After the video ends, Youtube offers up a number of them from other organizations.  Still cool, though.  O Fortuna seems to be getting a lot of play these days, in a lot of different media.

Wunderbar
