Alan Woods, of the International Marxist Tendency, speaks to University of Arts' London students at the Whitechapel Gallery, London, where a replica of Picasso's great painting of the massacre at Guernica is on display. Using this powerful masterpiece as a starting point, Alan explores what makes great art; to what extent is great art a reflection of the period from which it comes; and can propaganda be great art?

Alan Woods gives a lecture at the Chelsea College of Art in London in April 2009. He deals with the important role art plays in revolutionary political movements and speaks about how art changes to reflect the social and political events of the time.
