Nitsua's album "Soul of the Sky" was released in 2024. "Slow Light on a Feather" was released as a pre-release single. The original is a floating song centered around a dreamy and mellow piano, and is a comfortable piece that condenses Nitsua's fantastical worldview. Resonating with this worldview and the atmosphere of the song, a remix by haruka nakamura was realized. Starting with a guitar phrase and following the same chords, various sounds such as synths, guitars, and pianos shine, and the work unfolds more dramatically and beautifully, making it a masterpiece in which Nitsua's worldview and haruka nakamura's worldview are beautifully fused.
