TO1 (TOO) is only days away from their latest comeback!

On May 17 KST, the 'World Klass' rookie boy group unveiled the first music video teaser for their upcoming single "Son of Beast," the title track off of their 1st mini album 'RE:BORN.' In the clip, the members are seen at a car service garage, dressed in matching racecar driver-inspired outfits brandishing the group's logo on the back of their jackets. The song's funk beat can be heard in the background as they sing a short sample of the single's hook: "I'm a son of a beast."

Meanwhile, 'RE:BORN' is set for release on May 20.
