Korean improviser/electronic musician and 2024-2025 Roulette Resident Leo Chang presents a new evening-length performance with Peruvian interdisciplinary artist/researcher/robotics maker Efraín Rozas. Both of them use custom-built electronic instrument setups derived from their respective traditions as the basis for experimental rites—the audience will experience amplified gongs, robotic percussion, interactive lighting, and movement.
