Korean entertainment agencies’ “family concerts” and year-end special stages have always been the cross-group moments fans look forward to most. This time, HYBE is taking the surprise a step further with a brand-new collaborative single, “Iconic By Mistake,” created specifically for KATSEYE, LE SSERAFIM, and ILLIT.
According to the latest announcement on the official social channels, the new song will officially be released on June 12, while the music video will be unveiled first at midnight KST on June 11.
All three groups are currently at the height of their popularity. LE SSERAFIM recently released their full-length album “Pureflow Pt. 1” and its title track, “Boompala,” while ILLIT, known for their dreamy, girlish concept, are actively appearing on music shows with their new EP, “Mamihlapinatapai.” Then there’s KATSEYE, the international girl group co-managed by U.S. label Geffen Records, who recently took home awards including New Artist of the Year and Breakthrough Pop Artist at the American Music Awards – their momentum is remarkable.
What sparks will these very different girl-group styles create?
KATSEYE’s laid-back American edge, LE SSERAFIM’s signature fierce confidence, and ILLIT’s distinctive ethereal, quirky girlhood: how can these three aesthetics, which have developed along separate paths, blend naturally in one song and music video? More than simply piecing them together, it will test the production team’s skill.
Beyond anticipating the song’s release, fans are even more eager to see them perform on the same stage. The group has confirmed that this limited-time “super girl group” will give “Iconic By Mistake” its first promotional performance on the Korean music show “M Countdown” on June 11. If you follow Korean pop culture, mark the date on your calendar and tune in for this rare performance.
