Despite his status as a key figure in the history of Japanese ambient music, Hiroshi Yoshimura remains tragically under-known outside of his home country. Empire of Signs - a new imprint co-helmed by Maxwell August Croy, Spencer Doran and distributed by Light In The Attic - is proud to reissue Yoshimura's debut _Music for Nine Post Cards_ for the first time outside Japan in collaboration with Hiroshi's widow Yoko Yoshimura, with more reissues of Hiroshi's works to follow in the future. Working initially as a conceptual artist, the musical side of Yoshimura's artistic practice came to prominence in the post-Fluxus scene of late 1970s Tokyo alongside Akio Suzuki and Takehisa Kosugi, taking many subsequent turns within Japan's bubble economy afterward. His sound works took on many forms - commissioned fashion runway scores, soundtracking perfume, soundscapes for pre-fab houses, train station sound design - all existing not as side work but as logical extensions of his philosophy of sound. His work strived for serenity as an ideal, and this approach can be felt strongly on _Music for Nine Post Cards_. Home recorded on a minimal setup of keyboard and Fender Rhodes, _Music for Nine Post Cards_ was Yoshimura's first concrete collection of music, initially a demo recording given to the Hara Museum of Contemporary Art to be played within the building's architecture. This was not background music in the prior Japanese "BGM" sense of the word, but "environmental music", the literal translation of the Japanese term kankyō ongaku [環境音楽] given to Brian Eno's "ambient" music when it arrived in late 70's Japan. Yoshimura, along with his musical co-traveler Satoshi Ashikawa, searched for a new dialog between sound and space: music not as an external absolute, but as something that interlocks with a physical environment and shifts the listener's experience within it. Erik Satie's furniture music, R. Murray Schafer's concept of the soundscape and Eno's ambience all greatly informed their work, but the specific form of tranquil stasis presented on releases like _Nine Post Cards_ is still difficult to place within a specific tradition, remaining elusive and idiosyncratic despite the economy of it's construction. This record offers the perfect introduction to Hiroshi's unique and beautiful worldview: it's one that can be listened to - and lived in - endlessly.
