The rise of conceptual art in the former Soviet Union

It is one of the most influential schools of art to have emerged from the Soviet Union, which flourished under the arrival of Glasnost 20 years ago.

Moscow Conceptualism was anti-authority and avant-garde and seen as a controversial response to state-sponsored art which was hugely influenced by the West.

Now a major retrospective by some of the school's leading figures is at the Calvert 22 Gallery in London.
