The idol group CORTIS continued promotions for their 2nd mini album by delivering a standout live performance of the follow-up track ‘TNT’ after the title song ‘REDRED’.
CORTIS (Martin, James, Juhun, Sunghyun, Geonho) performed the title track ‘REDRED’ and the track ‘TNT’ in succession on MBC ‘Show! Music Core’ on the 9th and SBS ‘Inkigayo’ on the 10th. This was a new stage setup prepared for the first week after the release of the new album ‘GREENGREEN’. While ‘REDRED’ sparked a challenge craze on short-form platforms with its witty ‘Flappy Ears Dance’, ‘TNT’ channeled explosive passion from the group and fully showcased a raw edge.
‘TNT’ is a song about the confidence and grit of CORTIS regarding music and the stage. Its title, taken from the name of an explosive chemical, and an addictive melody flowing over fierce guitar lines and a weighty bass leave a strong impression. The members took part not only in the music-making but also in the choreography and music video production, adding authenticity. Gestures that directly embody lyrics such as “Nod your head” and “Pumpin up” stick in the mind.
A robust live band performance also drew attention. They appeared on the YouTube channel it’s Live to sing ‘REDRED’ and ‘TNT’. The band-arranged version made the textures of the bass and drums, as well as the searing guitar riffs that stood out in the original, feel even more vivid. The members roamed the space as if jumping with the audience at a music festival, enjoying the show.
At ‘KCON JAPAN 2026’, held on the 10th at Makuhari Messe in Chiba, Japan, they seized the main ‘M COUNTDOWN STAGE’ with overflowing energy. Despite it being their first KCON appearance since debut, they showed remarkable rapport with the local audience. The five members entered from the floor while singing the track ‘YOUNGCREATORCREW’, heating up the venue, then presented ‘REDRED’ and ‘TNT’ in succession to make their presence felt. Even while running across the wide stage, they executed both the group choreography and vocals flawlessly, earning raucous cheers.
This momentum translated into results. According to the record sales tally site Hanteo Chart on the 11th, first-week sales (one week after release) of the 2nd mini album ‘GREENGREEN’ reached 2,313,291 copies. That is more than five times the previous release and ranks second among first-week K-pop album sales released this year, following BTS.
Audiences can catch live stages for CORTIS 2nd mini album at university festivals: Dankook University Jukjeon Campus on the 13th and Hongik University Seoul Campus on the 14th. They will also keep up the momentum by additionally unveiling a performance for the track ‘ACAI’. The music video will be posted at 9 p.m. today (the 11th), and a conceptual performance film at 9 p.m. on the 12th, sequentially on the HYBE Labels YouTube channel.
