4Minute releases "Volume Up" MV

My Thoughts:
So I haven't seen the teasers or heard what the concept was for their comeback, but it looks like they jumped on the Shinwha vampire train. I should really figure out what the concept for this video is because I am seriously confused.

OVERALL IMPRESSION:
I really don't like 4Minute all that much but I knd of did enjoy this song. I might even get the mini album to see if it's any good.
