Cortis Tickets

Cortis became BigHit Music's first new boy group in six years, and the five-member act has rewritten the rookie record books since debuting in August 2025.

Their name comes from six letters in the phrase "Color Outside the Lines," and the group has leaned into that idea with punk-leaning energy and members who are deeply involved in writing and producing their own music.

Their first EP debuted at number 15 on the Billboard 200, the second-highest debut ever for a K-pop act's first album.

What to Expect from a Cortis Concert?

Cortis performances are fast, athletic, and built around sharp group choreography, with a young crowd that knows every lyric and every move.

The five members rap, sing, and dance, with Martin leading the rap line and Seonghyeon and Keonho anchoring the vocals.

The sound mixes hip-hop, pop-punk attitude, and bright hooks, so the energy rarely drops between songs.

Fan chants, light sticks, and call-and-response moments turn the crowd into part of the performance.

CORTIS's Biography

Cortis debuted on 18 August 2025 under BigHit Music, the label behind BTS and Tomorrow X Together, with the digital single "What You Want."

The lineup is Martin, James, Juhoon, Seonghyeon, and Keonho, who were between 16 and 20 years old at debut.

James had trained in BigHit's pre-debut group Trainee A, and Keonho was a competitive swimmer before joining the label.

Their debut EP Color Outside the Lines sold around 250,000 copies on its first day and passed two million sales, making them the second K-pop group ever to reach that mark with a debut album.

In 2026 they were named to Forbes' 30 Under 30 Asia list and earned their first music-show win with "REDRED."
