With the boys back in the motherland and with music shows returning to their original flow, boy group ZE:A brought the funk back to Music Core with their comeback track All Day. The group is taking on a tougher, more masculine image and surely fans won't complain! Their vocals and dance moves have also improved since their debut. These boys are taking things up a notch, especially due to the tough competition surrounding them. Check out the performance below! http://www.youtube.com/watch?v=DVjGeQCNuz4
