Two days ago, ZE:A collaborated with INFINITE and Dalmatian to bring "Music Bank" viewers a special treat for the fresh Spring season. Each group delivered crisp choreography that expressed their individual styles in both music and dance. ZE:A brought a sense of mystery and sophistication to their stage by wearing double masks so they could perform blindly. It was a huge hit, and netizens are still chattering about the sensational effect of their performance. A rehearsal video was uploaded onto the web, and it showed the boys tightening each point in their choreography. Although they're awkwardly spaced out at first, they eventually converge to stand more wholly as a unit. Check out their impressive video below! Tip: MoonJewel5
