The boys of BEAST were back on today's episode of Music Core to perform their latest hit track Shock! As usual, the performance was amazing as the boys shocked up the stage with their clean choreography and charismatic vocals. Check out their performance below. http://www.youtube.com/watch?v=UMhqtdXjx8U If you guys remember, near the end of BEAST's Shock MV, their was a scene where you can see the words "Coming up," "Next from CUBE" with the instrumentals of Just Before Shock playing. Well unfortunately, there's still no news about it, so let's just sit tight wait!
