When Tate Modern unveiled its innovative Turbine Hall twelve years ago, it forever changed the way the public experienced contemporary art. Now, they’re at it again with The Tanks, the inaugural phase of the museum’s long-awaited extension that seeks to bring live and performance art into the spotlight and into the arms of contemporary art viewers. The Tanks (which are in fact former oil tanks that were inherited from Bankside Power Station) also provide new ways for the medium to be studied, preserved, and showcased—in the past, displaying new media works have been an obstacle for the museum. Kicking off the innovative addition is Art in Action, a fifteen-week-long festival of live art, performance, installation, and film.

Art in Action will be on view at Tate Modern until October 28.
