Rainbow was not kidding when they said they were going for a completely new concept this time!

Although fans were already jumping out of their seats in excitement at the news of the group's first comeback in a year and eight months, they'll be even more possessed by the feels when they see the new MV trailer the girls dropped for "Black Swan."

Suiting the film of the same name, "Black Swan" introduces an eerie, psychological concept with contrasting themes, such as black and white.  The girls seem almost driven to insanity in this mysterious trailer as they grab their necks, make spastic movements, and gaze with wonder into the camera.  The background instrumental likewise has a mystical and eerie tone like a music box from a horror movie trailer!

Are you liking the concept so far?
