Many open-air performances are primarily about playing in front of a picturesque backdrop. Renae Shadler takes a different approach. The Australian choreographer, who has been living in Berlin for a long time, examines in her work how we shape our environment and how we are shaped by it. She performed the outdoor performance “Greyline”, organized by Radialsystem, in the Gleisdreieck park at the weekend in changeable weather. Dark clouds kept moving in front of the sun. The five dancers are prepared for anything, because wind and weather have a decisive influence on the course of the performance.
