Kahn has exhibited his installations in museums, galleries, art spaces and public sites internationally. These works focus on the idea of space: the conceptual and physical juncture points, its production and dissolution, and our relation to it as a political, social and environmental medium.

Kahn's other activities include sound pieces for radio, film, dance and theater. He has also designed numerous CD, LP and cassette covers. As a writer, his work has appeared in books, magazines and as liner notes to many audio publications.

Performing regularly around the world, Kahn has given concerts throughout Europe, North and South America, Australia, China, Egypt, Hong Kong, India, Indonesia, Israel, Japan, Korea, Lebanon, Malaysia, Mexico, New Zealand, Russia, Singapore, Taiwan, Turkey and South Africa.

In 2011 Kahn started the Editions imprint to publish his own recordings and writings."

"Toshimaru Nakamura is a Japanese musician, active in free improvisation and Japanese onkyo.

He began his career playing rock and roll guitar, but gradually explored other types of music, even abandoning guitar, and started working on circuit bending. He uses a mixing console as a live, interactive musical instrument: "Nakamura plays the 'no-input mixing board', connecting the input of the board to the output, then manipulating the resultant audio feedback."

Nakamura's music has been described as "sounds ranging from piercing high tones and shimmering whistles to galumphing, crackle-spattered bass patterns."

Nakamura founded the ensemble A Paragon of Beauty in 1992. He has recorded solo albums, worked as a session musician, and collaborated with artists including Sachiko M ("a kindred spirit"), Otomo Yoshihide, Keith Rowe, John Butcher, Nicholas Bussmann, Taku Sugimoto, Tetuzi Akiyama, dancer Kim Ito, and drummer Jason Kahn."
