Amazing video of the Arcade Fire playing in a freight elevator - then moving on into the crowd before getting on stage for a show. Taken from blogotheque.net - where they post a "Take Away Show" like this as a video podcast. The concept is pretty simple:

You meet a band. You take them outside, in the streets, and ask them to play there, shoot the movie in one unique shot, whatever happens. Those are the Take-Away Shows, the weekly Video podcast from french weblog La Blogothèque.

The spontaneity of it all seems to result in some very unique and amazing performances - like the Arcade Fire one. There are a number of other "Take Away Shows" on the site that are definitely worth checking out.

• The Shins take a stroll through a quiet neighborhood somewhere in France, on a sunny spring day - all the while entertaining passersby.
• The Cold War kids get pushed around on an equipment dolly - using walls, a truck and the floor as percussion.
• The National share a song around the supper table in a restaurant in Spain.
