One week ago, many kpop fans thought of TRAX as that one SM Entertainment group that fell through the cracks. Who knew that in a matter of days, the k-rock band would be back with a new mini-album? Fortunately for fans, the day they have been dreaming of has finally come, and TRAX really is back and breathing. With a mini-album release and multiple debut stages already under their belts, the duo has unleashed the music video for their leader track, Let You Go (??? ??? ??). Moments ago, SM Entertainment released the video on Youtube, and as the MV has turned out to be just as beautiful and enchanting as the teaser promised. As earlier reported, this music video features Super Junior's Heechul and f(x)'s leader Victoria.�Check it out here - oh, and have some tissues ready. http://www.youtube.com/watch?v=J7T8ywkwfbM What do you think of this music video?
