The masters of the cover are back at it and this time they take on A Great Big World's smash hit "Say Something". The original version has a lot of emotion packed into it already, so how do you make it even more powerful and emotional? I didn't think there was a way but Walk Off The Earth and their infinite depth of talent have managed to find a way. 

If you can't afford to watch the whole thing (shame on you because it's 3 minutes and 43 seconds long), at least watch until 2:39 because it's pretty sweet when everyone comes in and blows it up.
