Geinoh Yamashirogumi information

Geinoh Yamashirogumi (Japanese: 芸能山城組, Hepburn: Geinō Yamashirogumi) is a Japanese musical collective founded on January 19, 1974 by Tsutomu Ōhashi,^[1] consisting of hundreds of people with different occupations.

They are known for both their re-creations of globally-known folk music, along with music combining traditional and modern elements. Some fusions include an electronic recreation of traditional Indonesian gamelan music, due to MIDI digital synthesizers not being able to handle such tuning systems. Their 1986 album, Ecophony Rinne, introduced these computer-generated sounds. The success of this album brought them to the attention of Katsuhiro Ōtomo, who commissioned them to create the soundtrack of Akira.^[2] The soundtrack is built on the concept of recurrent themes or "modules". The soundtrack is a mix of digital synthesizers (Roland D-50 and Yamaha DX7-II, both of which could, by then, be tuned to the Pure-Minor, slendro, and pelog tuning scales), Indonesian bamboo percussion (jegog, etc.), traditional Japanese theatrical and spiritual music (Noh), European classical, and progressive rock.

The group's name uses Ōhashi's pseudonym, Shoji Yamashiro, and translates roughly to "Yamashiro Performing Arts Collective". Ōhashi took his inspiration from a postwar 1950s group of similar characters that lived as a commune.
