The Sums & Differences exhibition featured fourteen audiovisual works and twenty-six single-channel videos by Gary Hill, Steina, and Woody Vašulka. It was presented at the LÁ Museum in Hveragerði, Iceland, in 2022, and later at the Brno House of Arts in the Czech Republic in late 2023 and early 2024. The exhibition's preparation, research, and implementation carefully considered the acoustic characteristics of each venue, the available audiovisual technology, and how to position the artworks within the space to create an immersive and meaningful experience for the viewer while preserving the integrity of the works. This talk will explore the projects and methods that shaped the curatorial approach to Sums & Differences, along with the significant challenges involved in presenting audiovisual works spanning several decades in these unique gallery environments.
