“Space synthesis,” the debut solo show of German artist and composer Jan St. Werner, opens at Staatliche Kunsthalle Baden-Baden (DE). Known as half of musical duo Mouse on Mars, his recent projects include directional speaker experiments and “Alchemical,” a 2021 Bitforms exhibition with Casey Reas. Curated by Çağla Ilk, Werner activates the Kunsthalle’s acoustics with an installation that modulates sound and light, inviting visitors to explore and “become part of a moving, multi-perspective scenario.”
