Rookie boy band ChAOS returns in all their paint-splattered glory with “Racer,” the lead single off the group’s first mini album. The five members (Taeyang, Hyunsun, Heejae, Duhwan, and Dongmin) take their macho-dol image to the next level in “Racer,” trying out the gritty biker concept for this fatal dance track. As the intro speeds up to signal the start of the race, the boys set out to chase after the girl of their dreams.
