“The Stutter of History,” a retrospective of singular German sculptor-photographer Thomas Demand, opens at Shanghai’s Center for Contemporary Art (UCCA). Known for his meticulous cardboard reconstructions of real-world scenes, the show depicts “scenarios from the margins of historical events” including a meditation on the banality of Edward Snowden’s Russian hotel room (2021), and the squalor of the Stasi offices (1995, image), after being ransacked by German citizens.
