When I heard Bob Dylan reached out to Mumford and Sons and the Avett Brothers for a group performance, I actually got a little stoked on this years Grammys. Mumford and the Avetts both played one of their own tunes before joining Dylan for a rather rollicking take on Maggies Farm. The whole thing was great, but Mumford and Sons and the Avetts were the standouts of the nights broadcast. Really, Really good stuff. These guys got off the stage no more than an hour ago, and the video is already on the internet for your viewing pleasure.
