With Rubber tires piled in a corner and plastic water jugs hanging from the ceiling, The Curve at Barbican has been transformed into a conservationist’s nightmare. Pictures on the wall show people standing in the countryside with remanence of human intrusion. At the back of the exhibit is the main event; six screens that interweave the story of human existence and its relationship with the environment. John Akomfrah’s 'Purple' blends archival footage with his own material to create a montage of ideas and perspectives on the issue of climate change. The film is displayed over six screens and combines powerful visual and audio to shock the senses of the viewer. With so many different stimuli, the viewer must have a fine-tuned ability for finding the key aspects within the work.
