Watch Online Free on Watchseries. From Malevich’s “Black Square” to “Black Dog of St. Petersburg” — this is how DDT and filmmaker Sergei Kuznetsov defines the boundaries of the short 20th century. All the characters in the film are the heroes of DDT’s songs. Each episode is one track and one unique artistic method. The live‑action episodes alternate with chronicles, fragments of documentary films — both classic and little‑known — as well as with animation.
