Basel, Switzerland–based artist Kilian Rüthemann hand-built a red brick wall and installed it in the entryway to Mier Gallery’s project space, where it extends from the floor almost to the ceiling and curves in the middle as if casually leaning back. In the room behind the wall, Rüthemann attached smaller brick rectangles, about the size of windows, to the walls. A wall-length print shows a lone, 100-foot-tall fan palm tree standing in Exposition Park. Rüthemann chose this tree because of its age — 150 years — and the fact that it has been replanted three times over its lifetime. He was interested in how seemingly stationary monuments could also be tractable, and his show does manage to feel transitory on the whole. The leaning wall, held up just by gravity, looks as though it could topple at any moment.
