Even though they have yet to debut,�Dae Guk Nam Ah (D-NA for short) has been luring in a crowd of fans with their natural charm and musical talent. Many listeners have been taking interest in this five-man group not only because of the eye candy, but the fact that they seem to be taking a more a cappella, ballad-inclined route, at least for their first concept. The quintet's debut music video teaser has been released, and it looks like the rumors were right - the debut track seems to be a slow ballad of sorts. Check it out! http://www.youtube.com/watch?v=c60utdkePj4 Are you looking forward to this group's debut? They'll be kicking things off on Mnet M! Countdown on March 4, so stay tuned!
