After a shocking performance of their first comeback stage on yesterday's Music Bank, BEAST was back again for another comeback stage on today's Music Core! The boys had an outstanding stage as they performed Shock. Be prepared to be shocked by their performance below! http://www.youtube.com/watch?v=gzS1pAT_acI Although BEAST's Just Before Shock is my favorite song from their Shock of the New Era mini album, Shock is starting to get addicting the more I hear it. What do you guys think?
