“seesaw” is available now
Crush released the digital single “seesaw (feat. IU),” titled “삐그덕 (Feat. 아이유)” in Korean, on October 21, 2026. His announced release time was 6 p.m. KST. Apple Music confirms the date and lists a one-track R&B/Soul single.
IU is credited as the featured artist in the recording’s title. The catalog and Crush’s official channels provide listening references, while KPOP OFFICIAL links to the music video. The recording credit names P NATION, under license to Dreamus.
The GROUNDSEESAW project starts October 23
Crush’s official fan community also announced a collaboration with GROUNDSEESAW from October 23 to November 15, 2026. Visitors are invited to experience exhibitions with music specially prepared by Crush, giving the release a connection to physical art spaces.
The notice lists participating exhibitions at the Yongsan, Hannam, East and Central locations in Seoul. Opening schedules vary by exhibition, so the overall collaboration period should not be mistaken for identical daily hours at every venue. Check the relevant exhibition’s information before visiting.
Listening online and visiting in Seoul
For readers outside Korea, the single is the immediate entry point. The GROUNDSEESAW component offers a separate experience for visitors in Seoul. The notice does not announce a Crush–IU concert or promise that the artists will attend each exhibition.
The lead photograph shows Crush and IU in publicity material associated with “seesaw.” The article’s sources separately identify the recording, video and exhibition notice, helping readers distinguish online listening from the practical arrangements for a gallery visit.
