The 6 beastly men of BEAST perform "Mystery" today on MBC's Music Core.
Sporting blue and black tuxedos while showing off their powerful dance stage, it is another hot stage from the power rookies of 2009. Even their stage conduct is up to the professional level. AJ deals with a flop in his flip routine very well and you could barely tell that there was a little mistake. The boys just get better with every performance!
