I may be totally wrong, if so please correct me, but in the Soviet Union a lot of the artists were not treated well because they might cause dissent or another idea that doesnt go along with what the ruler wants.
I just feel like I remember something about many artists being suppressed during the USSR's reign.
Not to say they ALL were, but it was pretty censored.
Hell, look at Russia today, Pussy Riot, an all girl..."band" is heavily censored and targeted by the government for their anti-Soviet/anti-Putin views.
Yep. Read the Gulag Archipelago. Ir any good history of what they did to people that would not conform or be used as propaganda tools.
