K-pop group aespa released the official music video for 'Switchblade', their collaboration with Ty Dolla $ign, on August 4, 2026 — two days after the four-member group made their Lollapalooza debut at Grant Park in Chicago.

The video, published on aespa's official YouTube channel at 1 p.m. KST, leans into the group's 'kwangya' lore — a fictional universe that has run through aespa's music since their debut — to build a chaotic, lighthearted high-school world where members KARINA, GISELLE, WINTER and NINGNING play eccentric student characters. 'Switchblade' is a B-side track from the group's second studio album, LEMONADE, which was released on 29 May 2026 and entered the Billboard 200 — the flagship US album chart — at No. 9. The video's description carries streaming and download links for the album.

The timing was not accidental. On Sunday, August 2, aespa played their first-ever Lollapalooza set, a 14-song performance backed by a live band, DJ and dancers. The set opened with their debut single 'Black Mamba' and ran through fan favourites including 'Next Level', 'Armageddon', 'Supernova' and 'Whiplash'. Three tracks from LEMONADE got their live debuts: 'Can't Help Myself', 'SHAKIN'' and 'Switchblade' (Billboard).

Midway through the set, Ty Dolla $ign walked on stage to join the group for the first-ever live performance of 'Switchblade'. The American singer-rapper later called the appearance 'an incredible experience' and congratulated aespa on 'another unforgettable show'.

For fans, the video arrival extends the Lollapalooza moment into the week — a festival debut, a live collaboration with a US chart artist, and a fresh visual for an album track all landing inside three days. The video is available now on aespa's official YouTube channel.
