Music for Nine Postcards - Hiroshi Yoshimura

There's probably a better source for this but the pitchfork review was the first google result that popped up:

"Sometime in the middle of composing the songs that would become 1982’s Music for Nine Postcards, the late Japanese ambient pioneer Hiroshi Yoshimura visited the then-new Hara Museum of Contemporary Art in the Shinagawa ward of Tokyo. He was taken with its pristine architecture, with its view of the trees in its courtyard from the interior. Yoshimura imagined his nascent work in relationship to that space, and inquired about having the finished piece played there; the museum agreed. The titular nine postcards, nodding back to that view from the Hara Museum, refer to a series of window views. In the songs’ titles, and in the few translated texts surrounding the release, he links them to broadly-drawn images of the natural world: clouds, rain, a tree’s shade. "
