How CORTIS Is Rewriting the Idol Formula to Lead K-POP’s 5th Generation

In less than a year since debut, CORTIS has become one of K-POP's fastest-rising rookie acts. Their self-producing identity and relatable image have become defining parts of the group's appeal, but with creative participation now common across the industry, those traits alone may not explain the speed of their growth.

Self-production remains central to CORTIS' identity. The members have spoken about creating beats, melodies and lyrics together before collaborating with additional producers to further develop their songs. While more artists are taking part in songwriting and production today, what increasingly distinguishes CORTIS is not simply their creative participation but the degree to which audiences are invited into that process.

The group has livestreamed numerous beat-making sessions, allowing fans to watch creative discussions and early song development in real time. Even when these ideas never become officially released tracks, the openness of the process encourages audiences to engage with the group's music before it reaches its final form. One example is "NANI," a song created for Japanese broadcast "TV Asahi" during the promotions for their 2nd EP "GREENGREEN". As viewers watched the members build the track from scratch during the broadcast, interest quickly grew around the song itself.

Following the broadcast, "NANI" generated widespread discussion across social media. Fans created lyric videos, shared short-form edits and expressed hopes that the song would eventually receive a full official release. This level of audience participation benefits both sides. Fans become invested in the creative process, while the group receives immediate feedback before a song is formally released.

Furthermore, CORTIS' live performances increasingly suggest that their online popularity is translating into sustained offline support. While social media has played an important role in introducing the group to new listeners, recent domestic and international appearances point to growing audience engagement beyond digital platforms. Their first world tour, "PUT YOUR PHONE DOWN," sold out every released stop so far, while crowd participation at multiple performances suggests that casual online interest is developing into an established fanbase. Rather than relying solely on viral moments, CORTIS appears to be successfully converting online visibility into long-term audience growth.

CORTIS' public image has become another point of discussion among audiences as well. Rather than closely following familiar K-POP aesthetics, the group's musical direction, fashion styling and visual concepts frequently draw from alternative and Western youth culture. Their 2nd EP "GREEN GREEN" photo jacket, for example, incorporates imagery reminiscent of British bands such as Oasis and Blur, contributing to an identity that feels distinct from many contemporary idol groups.

This then is able to create a hybrid identity that appeals not only to K-POP fans but also to listeners who may not traditionally engage with idol music. Tracks such as "FaSHioN" and "GO!" illustrate this crossover. Many listeners have pointed to similarities with the production style associated with Pi'erre Bourne, who is widely credited with helping shape Playboi Carti's sound during the late 2010s. Likewise, CORTIS' use of wavy melodies, reverbed ad-libs and atmospheric production has prompted comparisons to elements found in Travis Scott's music. While these influences are not unique on their own, together they contribute to a musical identity that feels distinct from much of the current idol landscape.

Those influences have also contributed to differing reactions among audiences. For some K-POP listeners, these stylistic choices have been viewed as unconventional or at times excessive within the context of idol music. For others, particularly listeners outside the traditional K-POP audiences, they create a sense of familiarity through sounds that are already common within contemporary hip-hop and alternative music. Rather than fitting neatly into one category, CORTIS appears to operate somewhere between the conventions of K-POP and a broader alternative music culture, allowing the group to appeal across multiple listener communities.

Another notable aspect of CORTIS' positioning is how public discussion surrounding the group differs from previous BIGHIT MUSIC artists. With hitmanbang as main producer, groups such as BTS and TXT were always meant to have a stronger hip-hop presence, this presence however dwindled due to various things such as concept changes or an overall change in vision for the groups. When it comes to CORTIS though it seems this influence is stronger yet completely less visible. Moreover for previous BIGHIT MUSIC groups, Bang Si-hyuk has acted as chief executive producer and has always had a heavy involvement within the group’s vision, concept and narrative. Although he continues to serve as executive producer for CORTIS, discussion surrounding the group has largely centered on the members themselves rather than his involvement.

This may reflect a broader shift in how the group has been positioned. Rather than emphasizing the influence of a single producer, BIGHIT MUSIC has consistently highlighted member participation, collaboration and the YOUNGCREATORCREW system as central parts of CORTIS' identity. Whether intentional or not, this approach encourages audiences to focus on the members' creative contributions and the wider collaborative environment surrounding the group, rather than on a single figure directing their artistic vision.

At the same time, CORTIS' creative independence exists alongside the advantages of being part of HYBE. Behind the group's self-directed image is access to global marketing networks, industry partnerships, distribution infrastructure and creative resources that few rookie groups possess. These advantages do not diminish the members' involvement in the group's music. Instead, they provide the foundation that allows CORTIS to experiment creatively while operating within an established global system. The members themselves have repeatedly spoken about actively studying their musical influences and taking part in the group's songwriting and production, suggesting that both institutional support and individual initiative have shaped the group's development.

While CORTIS benefits from the opportunities that come with debuting under a major company, those same advantages have also created room for the members to actively shape their own artistic identity from the beginning of their careers. Rather than limiting creative participation, the group's environment appears to encourage it. If that philosophy continues to develop through the YOUNGCREATORCREW system, CORTIS may not only define its own path but also contribute to a broader shift in how future rookie groups approach creativity and artistic involvement. Whether that becomes a lasting model remains to be seen, but it suggests that placing artistry alongside commercial infrastructure does not have to be mutually exclusive.
