KATSEYE's Lollapalooza Argentina Debut: Sophia's Emotional Shoutout to Manon Steals the Show

On March 13, 2026, KATSEYE took the Samsung Stage at Hipódromo de San Isidro in Buenos Aires and delivered the kind of performance that turns a festival slot into a statement. Performing as a five-member group for the first time since Manon Bannerman's hiatus announcement three weeks earlier, Sophia Laforteza, Yoonchae, Daniela Avanzini, Lara Raj, and Megan Skiendiel powered through a 14-song, 50-minute set that proved KATSEYE at Lollapalooza Argentina 2026 was never going to be a diminished affair — it was going to be an elevation.

The moment that will define KATSEYE's Lollapalooza run came midway through the set. Sophia paused the music, turned to the crowd, and said simply: "Let's give it up for Manon!" The response was immediate and deafening — approximately 100,000 festival-goers erupted in cheers while fans in the front rows held up signs and light sticks for the absent sixth member. It was a gesture of solidarity that spoke louder than any prepared statement could have.

The KATSEYE Sophia Manon shoutout resonated across social media within minutes. Korean fan communities praised Sophia's leadership, with commenters on theqoo calling the five members "saints" for publicly supporting their bandmate despite the complicated circumstances surrounding Manon's departure from group activities. On February 20, HYBE and Geffen Records had announced Manon would take a temporary hiatus to focus on her health and wellbeing. Manon later posted: "I'm healthy, I'm okay, and I'm taking care of myself... Sometimes things unfold in ways we don't fully control" — a statement that fuelled fan speculation about the nature of the hiatus.

KATSEYE opened with a high-energy "CHAOTIC" intro before launching into "Debut" and "Gameboy," immediately establishing the tempo for the evening. The setlist drew from both their debut EP SIS (Soft Is Strong) and their recent project BEAUTIFUL CHAOS, threading together the group's evolution from polished newcomers to confident performers. "I'm Pretty," "Mean Girls," and "Tonight I Might" kept the crowd moving through the first half, while "Touch" and "Internet Girl" shifted the energy into sleeker, more atmospheric territory.

The back half escalated sharply. "Flame" brought theatrical intensity, followed by a surprise cover of the "Monster High Fright Song" that delighted the Buenos Aires crowd. The final stretch — Grammy-nominated tracks "Gabriela" and "My Way," followed by "M.I.A" and closer "Gnarly" — featured the evening's most elaborate dance breaks. Five members executed choreography originally designed for six with seamless precision, their formations adapted without ever feeling incomplete.

Lollapalooza Argentina carried personal significance for Daniela Avanzini, whose Cuban mother and Venezuelan father give her deep roots in Latin American culture. The crowd responded to Daniela with particular intensity throughout the set, recognising one of their own on the global stage. KATSEYE's multilingual appeal — the group counts American, Korean, Swiss-Japanese, and Latin American heritage among its members — translated naturally to a South American festival audience already primed for cross-cultural pop.

Argentina was only the beginning. KATSEYE performs at Lollapalooza Chile on March 14, followed by Lollapalooza Brasil in São Paulo on March 22 and a headline slot at Festival Estéreo Picnic in Bogotá, Colombia, on March 20. The South American run positions KATSEYE alongside headliners Sabrina Carpenter, Tyler the Creator, and Chappell Roan — a billing that reflects just how rapidly the group's global profile has expanded since their debut. Whether Manon will rejoin for any of the remaining dates remains unconfirmed, but if Buenos Aires was any indication, KATSEYE intend to honour her presence whether she is on stage or not.
