BigHit Music’s newest boy group, CORTIS, has officially arrived –– making a whole lot of noise even before their official debut on the K-pop scene.
The newly unveiled five-member group dropped their pre-debut track “GO!”, offering listeners and fans a high-octane preview of their upcoming debut EP, Color Outside the Lines. Together with the track’s release, an accompanying music video was also released –– featuring Y2K-influenced visuals set in Los Angeles, USA. Check it out in its entirety below:
According to BigHit Music, “GO!” introduces the group’s bold sonic identity, driven by a “minimal trap beat and sharp synth layers,”. All five members — Martin, James, Juhoon, Seonghyeon, and Keonho — have been credited in the creative process of the pre-debut single, reinforcing the group’s self-produced ethos. The label also described the newly released track as a “first declaration to the world to paint everything in the colors of CORTIS” ––an idea that resonates with both the title of their EP and the meaning behind the group’s name.
As announced by BigHit on the group’s Weverse site, CORTIS is set to officially debut on August 18 with lead single “What You Want,” which will also be included in their debut EP, Color Outside the Lines, this upcoming September 8, 2025.
CORTIS marks BigHit Music’s first new boy group since TOMORROW X TOGETHER debuted in 2019. The label — a subsidiary of HYBE, the powerhouse behind BTS — describes the quintet as “a crew of self-driven creatives who bring raw authenticity to everything they create, from music and choreography to video content.”
In other BigHit news, BTS recently reunited on a Weverse livestream following the fulfillment of their mandatory military service, confirming their highly anticipated 2026 reunion with a new album and world tour on the way. They also recently released their first live album, Permission To Dance On Stage – Live, which comprises 22 live performance tracks and serves as their first live album in their discography.
