GreenGreen

Cortis returns with GreenGreen, a six-track EP that finds the South Korean boy band leaning into a brighter, more organic sound. Released on May 4, 2026, through BigHit Music, the record trades the synth-heavy polish of their debut for warm acoustic textures and live instrumentation. The title track, "RedRed," leads the charge with its punchy guitar riffs and anthemic chorus, while deeper cuts like "Moss" and "Fern" explore themes of growth and renewal. The EP's sonic palette draws from indie pop and soft rock, giving the group room to showcase their vocal harmonies.

The release arrived after a whirlwind promotional cycle. Pre-orders opened on March 27, 2026, with the label promising "everything CORTIS stand for." The group's explosive music video for "TNT" dropped the same day as the EP, setting the tone for an era that Billboard described as "treating identity less as a fixed statement than as material to test and push into shape." GreenGreen stormed the charts upon release, topping the Circle Album Chart, landing at number two on the Oricon Albums Chart, and reaching number three on the Billboard 200. It marks a confident step forward for the group, proving they can shift gears without losing their identity. [edit]
