Wikipedia: Hiroshi Yoshimura (吉村弘, Yoshimura Hiroshi, 22 October 1940 – 23 October 2003) was a Japanese musician and composer. He is considered a pioneer of ambient music in Japan. His music lies mostly in the minimalist genre of kankyō ongaku, or environment music—soft electronic melodies infused with the sounds of nature: babbling brooks, steady rain, and morning birds.
In 2018, Crack Magazine selected his albums Green (1986) and Music For Nine Post Cards (1982) as the number 1 and number 7th most essential Japanese ambient albums, respectively.
[The latter reissued by Empire of Signs in 2017]
Spotify: "Yoshimura worked on integrating environmental music that combined graphic and sound design. He performed visual poetry, and worked on sound design construction for TOA, the storied Japanese manufacturer of amplifiers, signal processors, mixers, microphones, and speakers, while working on his own art in his spare time. In 1972 he started the computer music group Anonyme. He fell under the spell of Brian Eno's ambient music during the 1970s, because it mirrored his own core sonic and atmospheric discoveries. His iconic debut album, Music for Nine Postcards, was released in 1982 on Sound Process. It was originally recorded at home on Fender Rhodes and an analog synthesizer as a demo to be played in the Hara Museum of Contemporary Art. Produced by Satoshi Ashikawa. it was later subtitled Wave Notations 1 and released as the first of the historic but short-lived series -- the producer's Still Way (Wave Notation 2) was the other one."
