One of the most innovative and ambitious albums ever made, Geinoh 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, this four-part symphony of “ecological music” married ancient tradition with technological innovation, changing the way we listen in the process.

Half-speed mastered at Abbey Road Studios by Miles Showell, Time Capsule’s high-tech analogue reissue is the first to reproduce composer Tsutomu Ōhashi’s ground-breaking “Hypersonic Effect” theory on vinyl, cutting frequencies beyond human hearing into wax to capture the full emotional spectrum of this extraordinary work. Pressed on beautifully marbled dusty rose and muted sage green vinyl, each record carries a unique, smoke-like swirl pattern, making every copy as atmospheric and distinctive as the music itself.

Founded by polymath Ōhashi, also known as Shoji Yamashiro, Geinoh Yamashirogumi is a shapeshifting collective of over a hundred members spanning disciplines from neuroscience to engineering. Rejecting traditional professional musicianship, Ōhashi fostered a radical ethos where scientists, doctors, journalists and students critiqued society through expansive ethnomusicological performance, drawing on global traditions, Eastern spirituality and Western classical form.

Ecophony Rinne represents the pinnacle of this vision: an orchestral suite made with over 200 musicians, channeling Ōhashi’s ideas about humanity’s relationship with nature and the cycles of life, death and rebirth.

Pipe organ synths fashioned from sampled Tibetan horns sit alongside field recordings from Central African forests; Buddhist mantras circle dummy head microphones; Javanese Jegog percussion pulses like a living ecosystem; and the acoustics of temples, caves and landscapes resonate through the mix. Weaving culture, nature and technology together, it vibrates with the polyphony of life on Earth.

But Ecophony Rinne was not only musically radical. Observing differences between vinyl and CD editions, Ōhashi developed his “Hypersonic Effect” theory, proposing that ultra-high frequencies above 20kHz can influence perception even if inaudible. Listening becomes both physical and psychological: music felt as much as heard.

After its release, Ōhashi was approached by Katsuhiro Ōtomo to produce the soundtrack for Akira, the work for which Geinoh Yamashirogumi is best known. Emerging from the shadows, Ecophony Rinne stands as its transcendental blueprint, now reissued in its most complete hypersonic form on vinyl.

Rather than describe nature, it embodies it. Rather than reflect culture, it defines it. Rather than explore technology, it transforms it. You won’t have heard anything like it.
