*2022 repress* Three years have passed since the world first learned of Ursula Bogner's work. Since then, her identity has been surrounded by rumours, her graphic work have been exhibited (CEACC, Strasbourg, France, 2011 and elsewhere) and her compositional instructions have been performed (by Mo Loschelder, Andrew Pekler, Kassian Troyer, Holger Zapf, Jan Jelinek among others). The release of Sonne = Blackbox brings together all of these aspects and attempts to locate Ursula Bogner, the sound experimentalist within broader cultural history. A central theme is the phenomenon of fake: how did the erroneous suspicion of fakery come about in the case of Ursula Bogner and what is a post-fake?
