An exhibit of El Anatsui’s work spanning four decades was on display at the University of Edinburgh (Talbot Rice Gallery). The opening rooms featured his sculptural tapestries of made of disarded bottletops, alluding to colonial trade flows in West Africa. There were also woodcuts and prints, with collage, chine-collé, silver and gold foil. A bifurcated experience: beauty, at least from a distance, but disturbing symbolism in the materials up close.
