More can be written, but Brutalism in the Soviet Union was discussed in "Why do we associate Brutalist architecture with the Soviet Union?" by /u/kieslowskifan and /u/BeatMouse . It links to more discussion of Soviet brutalism, "Can anyone provide a historical context for Soviet urban planning?" , with further discussion by /u/International_KB and kieslowskifan (with book suggestions in various replies).

This is not to discourage discussion. More questions, data, and debate are welcome. The AskHistorians Politburo has not yet reached a decision. Let a hundred flowers bloom!
