aespa's Lollapalooza debut sparks praise and backlash

South Korean girl group aespa performed at Lollapalooza in Chicago on August 2, sharing the stage with American rapper Ty Dolla $ign for a live debut of their collaboration "Switchblade." The group released the song's music video shortly after the festival, and the set featured hits such as "Black Mamba," "Next Level," and tracks from their upcoming album Lemonade. The performance was streamed worldwide via Hulu, Disney+, and Weverse.

Social media reaction was divided. Fans highlighted the significance of a K‑pop act headlining a major U.S. festival, while a wave of viral posts labeled the set "boring" and likened it to a rehearsal, criticizing the group's vocals, dancing and stage presence. One comment read, "This is the most boring performance I've ever seen." The debate underscores the scrutiny K‑pop artists face when adapting to festival formats.
