The São Paulo Biennial, which opened on September 6, is traditionally a contemporary art festival, but this year’s event puts new emphasis on architecture. Chief curator Charles Esche commissioned nearly 70 percent of the exhibition’s artworks, collaborating with a five-person curatorial team that included an architect for the first time in the biennial’s 63-year history (fun fact: it’s the world’s second-oldest contemporary art biennial). — blouinartinfo.com
