Commissioned for the Engawa – Japanese Contemporary Art Season programme organized by Calouste Gulbenkian Museum's Modern Art Center, The Voice of Inconstant Savage is an immersive installation that superimposes a prayer inspired by the story of a 16th-century Portuguese missionary, a chant from a Kakure-Kirishitan (hidden Christians) prayer – a religion rooted in Nagasaki Prefecture –, a chant from the Karawara spirits of the Awá indigenous people – who live in the Amazon rainforest – and a chorus of Western Gregorian chant. Morinaga questions the position of the aesthetics of inconstancy in relation to the discourse of the “savage” that modern society confronts.
