Gosh that was pure mindfuck XD I actually listened to their song yesterday found it randomly in youtube. I thought "They look so... familiar, why?!" so I read a bit here and there and these guys are the DSP Boyz XD They released a lot of teasers on each member for their show and their temporary name was DSP Boyz and their official group name is A-JAX. Pretty random.
 
            

Their MV for Never Let Go ft. KARA's Goo Hara. This isn't the whole song 2 minutes it's missing dunno why O_O But here's the full ver.

They really put all the... *10 minutes later* afkjnskjd can't find the right word =__= koncentration? Focus...!! THAT'S THE ONE! DSP put all their focus on their singing abilities. Truly amazing! This is an interesting group ^^

 

Oh right! I also found the first episode on their show "DSP Boyz making the artist" (The same as MBLAQ) that was all the teasers for so here it is:
