K-Pop boy groups are practically popping up left and right nowadays, with shockingly young members, like in groups LNGSHOT, or in this case, CORTIS. Now, personally, it’s a little concerning to see groups like these with members that are around my age being taken out of school to become idols, but then again, it’s really cool to see other teenagers be able to pursue their dream careers at an early start in their lives.
CORTIS is a relatively new boy group in the K-Pop industry, debuting with their first extended play (EP) in Sept. 2025, “COLOR OUTSIDE THE LINES,” with hit songs, “GO!” and “FaSHioN.” The members’ ages range from 17 to 20. Martin (18), James (20), Juhoon (18), Seonghyeon/Sean (17), Keonho (17). Recently, as of May 4, 2026, CORTIS released their new EP, “GREENGREEN.” Although they released one of the songs, “REDRED,” as a single, as well as teased the song “YOUNGCREATORCREW,” continuously for one or two months on their social media, not to mention performing it at a few media events.
I think this EP expands the sound that they started to build in their first EP with “GO!” and “FaSHioN,” combining their electronic-type instrumentals with their fun and energetic rap. The most “high-energy” songs on the EP would probably have to be “REDRED” and “YOUNGCREATORCREW.” I think this EP is well-produced and very unique to them compared to some of the other groups in the industry, but of course, no hate to them either.
The EP slows down a bit with songs “Wassup” and “Blue Lips.” My personal favorite out of the three has to be “Wassup.” The song has a more mellow or chilled-out vibe to it, containing a more “lazy” type of rapping to it, while “Blue Lips” just has a vibe that isn’t my particular taste, but that doesn’t mean it’s a bad song.
CORTIS’s music overall is its own unique vibe that I would highly recommend to people who are trying to get into K-Pop that listen to a lot of rap music with influences from western artists like Travis Scott. The K-Pop industry lately has been extremely diverse in its genres of music, trying out different styles and concepts, and I think that it’s really cool to see these artists trying new things and not just sticking to the same sounds as most Western artists do these days, but maybe that’s just me.
