Radical Geometry: Modern Art of South America from the Patricia Phelps de Cisneros Collection, Royal Academy Sackler Wing, 5 July – 28 September 2014. Explores the innovative geometric abstract art that South American avant-garde artists created from the 1930s to the 1980s. The exhibition co-curated by Gabriel Pérez-Barreiro, Director of Patricia Phelps de Cisneros Collection in New York and Caracas, and Adrian Locke (of the Royal Academy, who curated last year’s RA exhibition of Mexican art 1910-1940), includes works by Argentinian, Brazilian, Uruguayan and Venezuelan artists. It investigates their relationship to the continent’s social, political and cultural circumstances, such as the links between modern geometries in 1930s and 1940s Uruguay and the work of Joaquín Torres-García and those of the ancient Inca. Other artists include the Brazilian Hélio Oiticica and Lygia Clark and Venezuelan op-artist Carlos Cruz-Diez
