This text deals specifically with Yugoslav experimental art practices. It investigates the relationship between negation practices across different art forms and media – literature, film, visual arts, radio – in former Yugoslavia (1918–2006), as well as the notion of artistic, economic, and symbolic values. Yugoslav experimental art practices are bearers of decolonial aesthetics and its radical epistemologies. Examining how they questioned, even deconstructed, existing ideologies (and their values) helps create a space for us today to operate both within and beyond specific ideologies with more freedom.
