EXO has surprised fans with a sudden release of a teaser video.

During the evening of December 3, the video, EXO 2015 COMING SOON, was released on SMTOWN's official Youtube channel and Facebook page. The popular group released the video as a preview of EXO's 2015 comeback and their new transformation.

Mazes, beads, and structures that form the EXO symbol seem to express EXO's identity and transformation symbolically. The black and white video does not feature any of the artists and heightens the viewers' curiosity of EXO's comeback.

On December 3, it was a victory for EXO at the 2014 MAMA, which was held at the Hong Kong AsiaWorld Expo Arena. EXO won a total of four awards, including "Singer of the Year" and "Album of the Year." This was the second year in a row that they won "Album of the Year." EXO also won "Male Group Award" and "Best Asian Style Award."

Last May, after releasing their second mini album, EXO ranked #1 on various music charts around the world with their title song, "Overdose," and received much love from their fans.

With EXO preparing new music and performances, their fans are hoping for the year 2015 to be another great year for EXO.

After a very successful first concert, "EXO FROM EXOPLANET #1 - THE LOST PLANET," EXO will be holding a concert during December 22 through December 24. This concert will be held at the Osaka Castle Hall, in Japan.
