El Anatsui has carved a name for himself with his monumental hanging sculptures made with recycled metal scraps. As imposing and spectacular as they are pliable and fragile, these works have been exhibited in some of the world's most prestigious institutions, most recently at Munich's Haus der Kunst and in the Venice Biennale's first Ghana Pavilion. Hours before the inauguration in Venice, Anatsui talked to Art Basel about the need to keep things light.
