The much-anticipated opening of the 2017 Venice Biennale is under way, and sneak previews of the show are already starting to flood in on social media. James Lee Byars’s giant Golden Tower is getting a lot of Instagram love, and the Anne Imhof performance, Faust, at the German Pavilion is attracting a buzz for its unique approach to capturing a sense of anxiety: bodies perform while encased, seemingly trapped, under a glass platform, and the pavilion itself is guarded by a fence and watch dogs. Some performers were spotted sitting on the fence, watching from above. Here, artnet News has rounded up the Instagram top posts ahead of the Biennale’s public opening on May 13th:
