From Discogs.com : "Klangkrieg is Felix Knoth (aka Felix Kubin) and Tim Buhre. Since 1990 Klangkrieg have been working on surround sound projection, text collages, audio art, music for theatre and film. In concerts the group combines analog sound processing and tape sounds with installation and performance elements, also including visual effects or even complete darkness. If possible they prefer to put people "into" the event by using multiphonic loudspeaker installations and surveillance cameras attached to their hands. Their basic sound origins are electronic and acoustic devices such as elevators, synthesizers, heatings, refridgerators and the inner string frame of an old dismantled piano."
"Radionik" was released by Cling Film Records in 1999.
