Haino sings. Hasunuma plays. It’s a minimal framework, but what emerges is a boundary-blurring sonic exploration. Across the album, Haino’s voice threads through Hasunuma’s layered soundscapes built from analog synths, electric guitar, piano, field recordings, and more. Haino entered the studio with only lyrics in hand, improvising melodies in response to Hasunuma’s evolving arrangements. The result is a work of deep trust, intuition, and sonic tension.

Keiji Haino and Shuta Hasunuma’s creative connection began in 2017 with an impromptu performance in Shibuya — Hasunuma on a Buchla modular synthesizer, Haino responding with the Japanese national anthem, »Kimigayo«. That moment sparked their unlikely collaboration. In 2018 Haino appeared at the Hasunuma-organized event »MUSIC TODAY IN KYOTO« at Rohm Theater, alongside Nobukazu Takemura, Manami Kakudo, Elena Tutatchikova, Kukangendai, among others. In September 2021 during the pandemic, the two performed »U　　　　　　　TA« for the first time at WWW in Shibuya. They began planning the album soon afterwards.

For the recording of »U　　　　　　　TA«, Haino entered the studio with only the lyrics in hand, with no knowledge of what sounds Hasunuma would produce. Responding to Hasunuma’s music in real time, Haino composed the melodies and layered in his voice on the spot. With additional sessions at Hasunuma’s private studio and Haino’s preferred studio, the album was completed.
