Leonid Tsvetkov is an Amsterdam based Russian-American artist best known for his site-specific installations, manufactured spaces, and research into residues, history, and the nature of change. His work investigates the frailty of physical, social, and conceptual boundaries, calling attention to the impermanence of landscapes, borders, and memory. A process-based artist, he employs archaeological deposits, consumer waste, electro-chemical reactions, social en-counters, and material interventions to create objects and landscapes designed to link place and memory, monument and event.
