CORTIS (MARTIN, JAMES, JUHOON, SEONGHYEON, and KEONHO) have released “REDRED,” the lead single from their upcoming 2nd EP GREENGREEN, offering an early preview of their expanding sonic direction.
Built around the contrast between what the group chooses to stand for and what they push back against, “REDRED” uses green and red as its central motif. The concept was first introduced by JAMES, with all five members contributing to the lyrics and composition, further anchoring the track in the group’s creative identity.
The track directly calls out behaviors such as following trends without question, seeking constant validation, and pretending to be cool. Instead, it reflects the group’s decision to move forward on their own terms. Ready to leap over the “fences” placed in front of them, they set out to follow their own path—marking the beginning of CORTIS stepping beyond expectations and carving out their own direction.

Sonically, “REDRED” leans into a raw, textural sound built around rugged synthesizer lines and a hypnotic, repetitive rhythm. Its direct lyricism and addictive hook further expand CORTIS’s distinct musical identity.
The performance was also built from the ground up by the members. Drawing inspiration from references including 1990s aerobics, shuffle dance, and tecktonik, they worked closely with the performance directing team to shape the final choreography. The result is a routine that visually echoes the lyrics while remaining instantly memorable. It is simple to follow yet unmistakably their own, positioning it as a performance designed for wide participation, following “GO!” from their previous EP COLOR OUTSIDE THE LINES.
The music video translates the track’s raw yet vibrant energy into a series of grounded, everyday moments. Set in familiar Korean spaces such as a neighborhood Korean BBQ spot, an arcade, and a vintage shop, it captures the members moving naturally through these environments, from grilling meat at a friend’s workplace to playing games and picking out outfits for one another.

Playful visual choices, including a grill-level point-of-view shot, fast-paced editing, and naturalistic performances, create a sequence of distinctive and memorable scenes. As with their previous work, the members first produced a self-made version of the video to map out its structure and tone, with key elements carrying through to the final cut and preserving their original creative direction.
The release builds on the strong momentum of their debut EP COLOR OUTSIDE THE LINES, which not only entered the Billboard 200 but also surpassed 2 million copies in global sales, marking the highest-selling debut album by a K-pop act on record. Anticipation for their return continues to grow, as pre-orders for their 2nd EP GREENGREEN has already surpassed 2 million copies in sales as of April 16. The project has also exceeded 750 thousand Spotify pre-saves, ranking No. 3 on the April 15 Spotify Countdown Global chart.
This summer, CORTIS will make their Lollapalooza debut, marking their first major U.S. festival performance. The group was announced last month as part of the 2026 lineup alongside Charli xcx, Tate McRae, Lorde, JENNIE, and other global acts. Notably, CORTIS is the only male K-pop act on this year’s bill. Lollapalooza 2026 will take place in Chicago, Illinois, from July 30 to August 2, with CORTIS performing on August 1.
Earlier this year, CORTIS further expanded their global presence by headlining the Opening Night of the NBA Crossover Concert Series during NBA All-Star 2026 as the first K-pop act to lead the event, before returning the following day for the NBA All-Star Game halftime show.
“REDRED” is now available worldwide on all streaming platforms, with a conceptual performance film to follow on April 21. Their 2nd EP GREENGREEN arrives May 4 at 6 PM KST.
About CORTIS
CORTIS—consisting of MARTIN, JAMES, JUHOON, SEONGHYEON, and KEONHO—have quickly solidified their position as a breakout global act under BIGHIT MUSIC since their debut in August 2025. The name CORTIS is an unconventional mix of six letters drawn from the phrase “COLOR OUTSIDE THE LINES,” reflecting their determination to think beyond the boundaries defined by the world. True to this ethos, the group has established itself as boundary-pushing originals who create on their own terms. Their 1st EP COLOR OUTSIDE THE LINES, released worldwide on September 8, 2025, landed at No. 15 on the Billboard 200, highlighting their rapid rise as one of the most talked-about new acts of the year. Earlier this year, CORTIS headlined the Opening Night of the NBA Crossover Concert Series during NBA All-Star 2026, becoming the first K-pop act to lead the event. The group continues the momentum with their 2nd EP GREENGREEN, led by the lead single “REDRED.”
