Truly an experimental documentary, Dziga Vertov’s masterpiece exemplifies the montage aesthetic of the Soviet avant-garde of the 1920s through its kinetic juxtaposition of shots and sped-up and slowed-down motion. Using his own concept of the "kino eye"—the cinema eye that illuminates the real world as not ordinarily seen—Vertov creates a city symphony depicting a day in the life of an urban metropolis.
