"Norbert Möslang (born October 6, 1952 in St. Gallen ) is a Swiss improvisational musician (soprano saxophone, double bass clarinet, live electronics) and violin maker.

Möslang had piano lessons. He then learned autodidactically soprano saxophone and double bass clarinet. From 1972 worked for 30 years with Andy Guhl in a duo; Since 1984 they went on the road as a voice crack. With Erik M and Günter Müller, the duo expanded into the ensemble poire_z.

Möslang increasingly used "cracked" everyday electronics in his improvisations; He intervenes in the circuitry of everyday objects, re-connects them, "cracks their code" as he calls it, and converts them into musical instruments. He also played with Barbetomagus, Jim O'Rourke, Otomo Yoshihide, Keith Rowe, Carlos Zingaro, Irene Schweizer, Kurt Liedwart and Jason Kahn. He also composes film music. For his work on Peter Liechti's documentary The Humours of Insects, he won the Swiss film prize in 2010.

Möslang also works as a photographer."

" is a musician, artist and writer. He was born 1960 in New York and grew up in Los Angeles. He re-located to Europe in 1990 and is currently based in Zürich.

As an electronic musician, vocalist and drummer Kahn collaborates regularly with many musicians, both in improvised settings and in the context of graphical scores which he composes for specific groups.

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."
