At Manchester Art Gallery you can see large scale works which explore ideas of trade and cultural exchange and issues of migration and freedom of movement. Barthélémy Toguo’s enormous new commission Redemption, El Anatsui’s dazzling multi coloured textile sculpture and Nnenna Okore’s vast wall sculpture When the Heavens Meet dominate the main gallery. Another room is devoted to environmental issues explored from different angles with film, photography and painting. There are also works scattered throughout the historic building. Look out for Aboubakar Fofana’s new commission Obsession suspended from the atrium ceiling, Romuald Hazoumè’s masks, Emeka Ogboh’s soundwork outside the front door and Pascale Marthine Tayou’s Poupées Pascale (Pascale’s Dolls) which infect the historic galleries like a ‘colonial perfume’.
