Performance and installation artist Tomás Saraceno (AR) collaborates with engineers, architects, and biologists and addresses issues such as the increasing uninhabitability of the earth in his installations. Like Hamburg, the city of Venice has developed an alarm system to warn of flooding. Saraceno’s sound work Acqua Alta: En Clave de Sol, with which he was represented at the 2019 Biennale di Venezia, speculates on what the floating city might sound like a hundred years from now, when its vulnerable ecology is completely submerged beneath the fast-flowing tides and its foundations have been eroded by overexploitation of soil and water.
