Runner-up on Mnet's 'Superstar K3' trio Busker Busker took the stage today on 'M! Countdown' to put on their first live stage performance ever.

Although the group's appearance today is classified as just a special stage in order to promote the upcoming 'Superstar K4', the boys will be making their official debut near the end of March or early April.

Check out the boys as they rock the stage with their fierce moves and vocals in "Makgulina" below, and be sure to check out the rest of today's 'M! Countdown' performances here!
