Rodchenko and Popova: Defining Constructivism29.04.2009 Tate Modern’s exhibition explores the work of Aleksandr Rodchenko and Liubov Popova, who sparked a revolution in Russian art. The Constructivists challenged the idea of the work of art as a unique commodity, and believed that it could contribute to everyday life through design, architecture, theatre and film.  In this interview, one of the show’s curators Ben Borthwick looks at how their paintings, however abstract, can still be mapped back to things that exist in the real world.
