A wonderful examination of the power of art to defy tyranny, using not only the voices of the dissident poets including Boris Pasternak as well as Osip Mandelstam, but of ordinary Russians caught up in Stalin's purges. My favourite voice is that of Fikrit Shotman, whose humour, courage and uncomplaining acceptance of the madness of his world seems to me to be truly that of most Russians at the time.
