“Imagine 15 to 20 angels flying through the air on zip-lines stretching from the opera roof and cranes around the square Gustav Adolfs torg, followed by a sea of feathers floating down over the audience,”says Claes Karlsson, creative director at Stockholm Culture Festival. The scenario he describes is not a dream, but a performance by the street company Gratte Ciel, whose Place des Anges show has previously been seen in Marseille and London’s Piccadilly Circus. This summer the group is one of the headliners at Stockholm Culture Festival on 16–21 August, presented in collaboration with the Stockholm Chamber of Commerce and Institut Français.
