Product Description

The first album from virtual singer/rapper SAK!

Since suddenly emerging onto the digital music scene in July 2025, SAK has steadily released new music and was selected to perform a TV anime theme song in 2026. Backed by HYPERPOP and FUTURE BASS influences, SAK has established a unique presence as a virtual singer/rapper, blending pop and dreamy aesthetics with a distinctive edge.

This long-awaited debut album showcases SAK's melodic, floating vocal flow against an electronic soundscape. The project features contributions from leading creators in Japan's club music scene, including Daoko, KOTONOHOUSE, Pa's Lam System, Yaca, hirihiri, Hidefumi Kenmochi, and maeshima soshi, as well as rising producers from the internet music scene such as Police Piccadilly, R Sound Design, biz, and ZERA.

Across 10 tracks, the album radiates an overwhelming worldview and dazzling brilliance, channeling an energy like backlight breaking through as an alternative to existing music scenes.
