Made in 1926 as a tribute to Soviet resources and to its people, One Sixth of the World contains footage shot by Vertov’­s cameramen from the Arctic Circle to the Chinese border, from the Black Sea to the Sea of Okhotsk. 1930’­s Enthusiasm, Symphony of the Don Basin, “the most significant contribution to the Soviet sound film” according to Annette Michelson, is a gorgeous atonal celebration of Soviet coal mining, as the workers achieve their Five Year Plan quota in a mere four years. Charlie Chaplin said: “Never had I known that these mechanical sounds could be arranged to sound so beautifully. I regard it as one of the most exhilarating symphonies I have heard.” Restored by Peter Kubelka! (Irina Leimbacher)
