BE:FIRST has released the music video for "WATCH ME feat. BIA," the lead track from their global EP "WATCH ME," released on September 18.

The EP is BE:FIRST's U.S. debut release and was created under producer SKY-HI in collaboration with international partners.

"WATCH ME" features American rapper BIA, with choreography by BE:FIRST member SOTA and choreographer ReiNa, who previously worked together on "Mainstream" and "Masterplan."

Based on an original concept by SOTA, the music video takes a freestyle approach that highlights the members' humor and natural groove.
