Hiroshi Yoshimura - Music For Nine Post Cards (Wave Notation 1) † [1982, full album]
Yoshimura time! All-round good egg, and a certified Eno-head. Maybe you could call this the opening act of Yoshimura's life-long trademark of filling small spaces with warm notes. It was his first full-length album, coming out as the first part of Satoshi Ashikawa's short-lived but influential Wave Notation project.
