"Spring" is a collaborative album by these four musicians. Each of them separately recorded a solo performance in March 2025, and the recordings were mixed by Prins (track 1), Eubanks (2) and Nakamura (3 and 4) respectively, resulting in the four tracks on this album. Eubanks played soprano saxophone, electronics and modular synthesizer; Prins made use of electronics and percussion; Akiyama played guitar; and Nakamura used the no-input mixing board. The album sleeve features a composite of four photos of spring flowers, taken individually by the four musicians near their respective homes.
