It all started with a simple tweet from the band that asked what New Orleans was up to, and ending up being a kick ass rock show.

Of course, we know there's a new documentary series set to be recorded, and rumor has it that the performance in New Orleans was supposed to be for HBO use as well.

Either way, these surprise Foo shows are pretty awesome, and the video shows some spur of the moment ecstasy from the crowd, which is pretty refreshing in and of itself.

Keep your Twitter tuned the Foo...you just never know where they could strike next.
