This might be the first time ever hearing about Double K, but it seems like everyone knows Seo In Guk and Dok2. Double K released their new song OMG, you will feel like you're in a party for sure.

These men are making the party or club AWESOME! All of their voices really fit with each other and with the song as well. Oh wait, did you see that woman? OMG I think that was Jessi!

Also why is Seo In Guk always next to a wall, by himself, do the ladies not appreciate his voice? This trio is pretty good, they should defiantly make more music together cause it will be good!
