CORTIS is making a surprise appearance on Mnet's M Countdown on February 5.

The group will perform "JoyRide," a B-side from their debut album COLOR OUTSIDE THE LINES. All members participated in writing and composing the track, blending the lyrical, addictive qualities of alternative rock. This marks the song's first-ever performance on a music show.

Big Hit Music stated, "This stage was prepared to give back for the continued love shown to the debut album. It reflects the members' desire to thank fans with a powerful performance."

On the same day, members Martin, James, and Sunghyun will also serve as special MCs. It will be their first time hosting since debut, offering a different side of their charm beyond the stage.

Meanwhile, CORTIS is set to headline the NBA Crossover Concert Series on February 13 at the Los Angeles Convention Center.
