KATSEYE performed their song "GNARLY" (with an extended dance break) at the 2026 Grammy Awards during the Best New Artist segment. This was their debut performance on the main Grammy stage, and it came shortly after their 2024 debut under HYBE x Geffen Records as a global girl group.

shows high-energy choreography, sharp formations, and the group delivering a remixed version with some lyric tweaks and a powerful dance-focused section. It received strong engagement overall: over 51K likes, 7.9K reposts, and 1.6M views on that post alone.Fan reactions are pretty divided:
  • Many praised the dance break and stage presence, calling it energetic, "gaggy," and impressive (especially the synchronization and power from members like Yoonchae and others).
  • Positive comments highlighted their talent, confidence, and how they owned the stage.
  • On the flip side, a noticeable portion of viewers (including some casual observers and newer fans) wished they had chosen a different track instead, like "Gabriela", "Debut", "Touch", or "Game Boy" — feeling "GNARLY" didn't showcase their full range or vocals as well for such a big moment.
  • Some criticism focused on the song's lyrics/production feeling basic or mismatched for a Grammy spotlight, with comments like "4th grade flash card lyrics" or wishing for stronger creative direction.
Media coverage (e.g., Forbes called it a "high-octane" performance that "stole the show" with its explosive energy, while outlets like Variety and Entertainment Tonight highlighted the moment positively) leaned toward celebrating their impact and the crowd's response.Overall, it seems like a bold, polarizing choice that got people talking — the performance definitely made noise during Grammy night!If you'd like more details (e.g., about the Best New Artist outcome, full reactions, or related clips), just let me know. 😊
