One of the most innovative and ambitious albums ever made, Genioh Yamashirogumi’s Ecophony Rinne is a sonic masterpiece featuring over 200 musicians that expanded the limits of what music and sound could do.

Before Akira there was Ecophony Rinne. Originally released in 1986, Ecophony Rinne is a four-part symphony of “ecological music” by Geinoh Yamashirogumi that married ancient tradition with technological innovation, and changed the way we listen to music in the process.

Half-speed mastered at Abbey Road by Miles Showell, Time Capsule’s high-tech analogue reissue is the first to reproduce composer Ōhashi’s ground-breaking “Hypersonic Effect” theory on vinyl, cutting frequencies beyond the realm of human hearing into wax to capture the full spectrum emotional impact of this extraordinary work.

Founded by genius polymath Tsutomu Ōhashi aka Shoji Yamashiro, Geinoh Yamashirogumi is a shapeshifting collective of over a hundred members from across disciplines. Rejecting professional musicianship, Ōhashi cultivated an ethos where neuroscientists, psychologists, doctors, journalists, engineers and students could critique society through artistic expression and pursue their research in ethnomusicological performances that spanned global traditions, Eastern spirituality and Western classical form.

Ecophony Rinne represents the pinnacle of this vision - an expansive orchestral suite made with over 200 musicians that channeled Ōhashi’s thinking about mankind’s relationship with nature, and fundamental questions of life, death and rebirth.

Here pipe organ synths made from sampled Tibetan horns sit alongside field recordings from Central African forests, Buddhist mantras circle dummy head microphones, Javanese Jegog percussion ensembles pulse like verdant ecosystems, and the acoustics of temples, caves and landscapes are conveyed in the mix. Weaving together culture, nature and technology, it is a record that vibrates with the polyphony of life on Earth.

But Ecophony Rinne was not only musically innovative. Noticing the difference between vinyl and CD versions of the album where digital reproduction limited the sound, Ōhashi developed a theory of “Hypersonic Effect”, determining that ultra-high frequencies above 20khz can impact human perception even if they are inaudible. At once a physical and a psychological experience, to listen to Ecophony Rinne is to feel music differently.

The rest is history. After its release, Ōhashi was approached by director Katsuhiro Ōtomo to produce the soundtrack for Akira, the work for which Geinoh Yamashirogumi is best known. Emerging from the shadows at last, Ecophony Rinne was its transcendental blueprint, reissued in its most complete hypersonic form on vinyl for the first time.

Rather than describe nature, Ecophony Rinne embodied it. Rather than reflect culture, Ecophony Rinne defined it. Rather than explore technology, Ecophony Rinne changed it. As a work of art, it is more relevant than ever. You won’t have heard anything like it.
