Julie Dossavi, a Benin-born, French-based choreographer (with Gerard Gourdot) and dancer, produces in Go one of the most compelling, charismatic performances on display anywhere. Go begins slowly, to traditional African pipes. Dossavi is starkly silhouetted against a burning orange backdrop, a shadow in profile. Gradually she moves across the stage, using extraordinary extensions of the hands and neck in ritualised, repetitive gestures. The tempos alter and from African tradition we move to the techno-beat of modern urban life. Dossavi moves with it, alternating between a trance-like state of pure movement, joy in the dance, glee in performance, and the anxiety and isolation of modern life.
