The original version of 'Shinshunfu' was composed by Kohei Amada and played by an ensemble in which the Japanese traditional instruments koto, sho and taiko fuse perfectly with the Irish harp. The composition itself also melds Amada's traditional, classical sensibilities and his knowledge of the deepest roots of Japanese music with his appreciation of new developments in both Japanese and Western music. Side B contains a 2018 rework by Sugai Ken.
