The coupling track for MCZ's new song has been released.

The coupling track "Cosmic Commotion" from MCZ's 23rd single "Event Horizon" (released July 23, 2025) is available for pre-sale today on all major music distribution platforms. (See link to Spotify at bottom.)

The song was composed and arranged by the music unit PAS TASTA and the distribution jacket was designed by visual artist watakemi.

The song features a "cutting-edge digital sound" and the lyrics incorporate Momo clo's "ever-changing attitude" as the group enters its 18th year of existence.

According to PAS TASTA's comments, the song brings out a new side of Momo clo while utilizing their signature electronic and experimental sound.

PAS TASTA is a six-member music unit founded in 2022 and has been selected for Spotify's "RADAR: Early Noise 2025," and is attracting attention as a next-generation artist, 

TV commercials, collaborative PVs between Hololive and the Los Angeles Dodgers, etc. They have been active in a wide range of projects, but this is the first time for them to provide a song for a major idol group, and we are eagerly awaiting their evaluation.
