Bringing The Crowd To Its Feet

One of those fun things that shows up on your Facebook page. Just under 5 minute video of a couple of cello players that go in front of an audience expecting heavy metal, or some such. They're nearly booed off stage until they get going. Then the audience ends up on its feet.

Addendum: I see one commenter to the Facebook post claiming it was staged to make the video. Maybe so, but still pretty cool.
