Primary Information has reprinted Broken Music, a crucial compendium for records that was created by visual artists. The book was edited by Ursula Block and Michael Glasmeier and originally published in 1989 by DAAD. The book contains essays by the two editors as well as Theodor W. Adorno, René Block, Jean Dubuffet, Milan Knizak, László Moholy-Nagy, Christiane Seiffert, and Hans Rudolf Zeller. The book also comes with a flexi disc containing a performance of Knizak's "Broken Music" by the Arditti Quartet.
