Architectural Digest. Elle Decor. Houzz, an online community of more than 40 million residential design enthusiasts around the world. House porn, it’s safe to say, is an international obsession and lucrative business. But how often does anyone, much less a curator with a selected roster of artists, delve into the culture, history, symbolism, and materiality of interior design and decor? The discourse starts here, with “Question the Wall Itself.” According to Fionn Meade, exhibition curator and Walker Art Center artistic director, “The exhibition takes as its guiding principle what Belgian artist and poet Marcel Broodthaers termed ‘Esprit Décor,’ a critique of ideas of nationality, the effects of globalization, and the space of the institution through constructed interior scenes.” When is an interior a home? A set or stage? Or a lifestyle prop? How will sculpture, performance, installations, and photographs from 23 international artists cast a global lens on how we read a room? And we’re not just talking houses. Prison cells (paging Foucault), libraries, showrooms, and interior gardens are also examined.
