The rhythm of joy played by grandfather Geek, when he was 75 years old, he remodeled his Japanese-style room into a completely soundproof recording room.With the members of"Hyakki Yaon" formed from the gathering of the old people's association with like-minded friends, we devised a detailed planning composition and spent four years producing this album"Particles", fighting against the country of Yomi. Please enjoy the groovy sound of a stylish man.
