What Have They Done with All the Air?, a stirring new exhibition by William Kentridge, features works that form part of his new theatre production in the making, in which the famous Johannesburg-based artist and Design Indaba alum uses the setting of a boat as a prompt for unpacking issues of power, colonialism and migration. The upcoming theatre production, The Great Yes, The Great No, employs the technique where actors perform against green screens so backgrounds can be added later.
