Object in focus: Back of Gbenga's Head by Nahem Shoa

'Back of Gbenga's Head' sits proudly and stoically amongst the other portraits in room five at Walker Art Gallery. Its placement is a direct call out to the man next to him, Richard Gildart, who was heavily involved in the transatlantic slave trade. Hear from Nahem Shoa, the artist behind the monolithic work, about the importance of representation on gallery walls.
