Defy gravity, literally. Rock climbing meets acrobatics meets dance in AscenDance Project's Beyond Gravity. Founded in 2006 by German-born performance artist and mountaineer Isabel von Rittberg, the AscenDance Project explores the aesthetics of rock climbing with dancers performing on a vertical stage. Their 2008 world premiere in SF's very own Union Square set the stage for many future performances to come. Using a 24-foot-long and 12-foot-high climbing wall, AscenDance artists move through three dimensions, using time and space as variables. Dancers prove their ability to overcome gravity—no ropes, no harnesses, just sheer strength.
