This article provides a reflective overview of What Lies Unspoken: Sounding the Colonial Archive, a sound intervention which I initiated and produced in collaboration with curators at the Statens Museum for Kunst and Royal Library of Denmark, whilst conducting artistic research within the Living Archives Research Project at Malmö University. The project was part of commemorative activities during 2017, marking the centennial of the sale and transfer of Denmark’s former Caribbean sugar colonies (St Croix, St Thomas, and St John) to the United States. The intervention aimed to address the uncomfortable silences surrounding institutional and societal engagements with colonial history in Denmark. In the article I describe how and under what particular cultural conditions this project was developed, share some of the thinking that underpinned its making, and finally reflect on the realities of what it takes for cultural heritage institutions to share interpretive power.
