K-Pop rookies Cortis have TikTok buzzing with the choreography for their breakout track “Go!”
The single, taken from their debut EP Color Outside the Lines, is still viral on TikTok more than a month after its release thanks to its high-energy choreography and addictive chorus.
The group, made up of members James, 19, Juhoon, 17, Martin, 17, Seonghyeon, 16, and Keonho, 16, made their debut in August under BigHit Music, the label behind superstars BTS. Cortis is also the label's first new boy group to debut since Tomorrow x Together in 2019.
Since the release of “Go!,” stars like BTS’ J-Hope and Katseye members Lara and Yoonchae have joined in on the viral dance challenge. A TikTok-famous weatherman and even a mariachi musician have jumped on the bandwagon, in addition to a legion of fans performing the dance on the platform.
Take a look at the best dance covers of Cortis’ “Go!” below.
As a bonus, this fan brilliantly mashed up the choreography with Travis Scott’s “FE!N.”
Cortis’ debut EP, Color Outside the Lines, arrived on Sept. 8 and entered the Billboard 200 at No. 15. The EP also features an English version of their pre-release track “What You Want” featuring Teezo Touchdown.
