“Tangent” is a stage masterpiece led by Japanese media artist Shiro Takatani. The work synthesizes Takatani's three decades of interdisciplinary artistic exploration across installation art, theater, and modern dance, pioneering a new expressive form in contemporary performing arts.

Centered on the theme of “liminal space,” the piece delves into the perceptual boundaries between reality and the surreal. Through meticulous light and shadow design and soundscape construction, it creates a unique perceptual field that blurs the boundaries of time and space. Takatani redefines the cognitive limits of “visibility” and “invisibility” by artistically recreating natural phenomena—such as the refraction of light in morning mist and the representation of seismic vibration frequencies—guiding audiences into an artistic realm beyond the everyday.

Breaking free from traditional stage performance constraints, “Tangent” employs motion-controlled cameras to track the performer in real time, capturing electric sparks and synchronizing their light trails with the performer's body language. The piece employs an 18.4-channel immersive sound system and pendulum audio feedback devices, forming rhythmic feedback loops with the performer's voice to create distinctive sonic patterns. This profound fusion of technology and artistry not only delivers an immersive viewing experience but also imbues each performance with unique vitality.

The music featured in this work is selected from the late artist Ryuichi Sakamoto's final album, “12”. Ryuichi Sakamoto participated as a new member in Dumb Type's creation for the 2022 Venice Biennale, under Shiro Takatani’s artistic direction. The late master's music, with its profound emotion and distinctive musical language, forms a subtle resonance with the work's visual expression. This cross-disciplinary artistic collaboration not only continues the deep artistic dialogue between Dumb Type and Sakamoto but also imbues the work with an immortal artistic soul.

“Tangent” is not merely an innovative experiment in artistic form and technics; it is a profound reflection on the relationship between human beings and nature, technology and humanism. It offers audiences a unique opportunity to reexamine the boundaries between human perception and the real world.

Dumb Type

Artist Collective

Dumb Type was founded in Kyoto in 1984, with founding members including Teiji Furuhashi, Shiro Takatani, Toru Koyamada, Yukihiro Hozumi, Misako Yabuuchi and Hiromasa Tomari. As a globally acclaimed media art collective, its early interdisciplinary works include Pleasure Life (1988), pH (1990–1995) and S/N (1992–1996). Since the 1990s, with the join of new members such as Ryoji Ikeda and under the direction of Shiro Takatani, Dumb Type has continued to create works including OR (1997–1999), memorandum (1999–2003), Voyage (2002–2009), and the related installations.

Their first large-scale solo exhibition, DUMB TYPE: ACTIONS + REFLECTIONS was held at Centre Pompidou-Metz in 2018. In 2022, Dumb Type created a new installation 2022 for the Japan Pavilion at the 59th Venice Biennale, welcoming Ryuichi Sakamoto as a new member. The related live concert 2022: remix was presented at the Teatro Goldoni in Venice. Also, the related exhibition 2022: remap was held at the Artizon Museum in Tokyo in 2023.

Ryuichi Sakamoto

Music

Ryuichi Sakamoto (1952–2023) was a composer, producer, and artist born in Tokyo. His diverse career spanned pioneering electronic works with Yellow Magic Orchestra, pop albums, classical compositions, two operas, and nearly 45 film and TV scores.

Sakamoto made significant contributions to the art world through installations and exhibitions in galleries and museums worldwide. The most comprehensive survey of his artworks was exhibited at the Museum of Contemporary Art Tokyo from December 2024 to March 2025, becoming the most visited exhibition in the museum's 30-year history.

On his 71st birthday, January 17th, 2023, Sakamoto released 12, his 15th solo album. This collection of twelve songs came from musical sketches he recorded like a sound diary during his two-and-a-half-year battle with cancer. Unable to perform live in his final years, he gathered his energy in late 2022 for one final performance: Ryuichi Sakamoto | Opus.

Ryuichi Sakamoto passed away in March 2023 at the age of 71.
