What comes to mind when you think about East Germany during the Cold War? Transnational black experimentalism? On today’s episode of Sound It Out historical musicologist Harald Kisiedu traces the development of experimental jazz through the innovative musical dynamo Ernst-Ludwig Petrowsky. Kisiedu shows how the institutional discourses of the time pinpoint aesthetics as a critical location for the negotiation of political values, particularly surrounding imperialism, democracy, the West, and the Soviet Union. Hear about socialist realism, the specter of decadence, and the rooting of experimentalist influences from the United States in this meticulously researched lesser-known history of an important branch of experimentalism as a transnational phenomenon.
