Actually,you'd be surprised - but it's not because of communism but in spite of it. As people had to watch what they did/said in the public and sometimes among friends and family, they tended to withdraw to the private sphere, often focusing on solitary pursuits such as music and literature.
It was a coping mechanism, withdrawing to your own private world. Otherwise you'd go crazy with all that oppression and absurdity. And it's not that you had much option to channel your creative energies - you couldn't travel or own a business, and if you were not great at sports or were unfit for the higher levels of the military-bureaucratic complex (in USSR then usually meant Jewish or a darker skin tone) your options were very limited. That's why you had to many exceptional composers and classical musicians in the USSR.
Also, people believed you were less likely to get into trouble with the authorities by being a musician, considered a "safe" profession. Not the case, though.
Some art forms were straight out prohibited or overtly discouraged (poetry, modern art...) but many talented individuals found a way to showcase their talent by serving the regime - filmmakers come to mind. For every one hundred idiotic Soviet propaganda movies there came a veritable masterpiece.
Another bizarre effect of this was the explosion of science fiction and what is today know as fantasy literature in the former Eastern Bloc.
As writing about politics or even regular daily life (outside the idealistic propaganda bullshit) could get you arrested, science fiction and fantasy was the way out. Writing about the grim reality of Soviet life or housing shortages - penal colony in Siberia, writing about interstellar travel or elves - slightly disapproving looks by the government censors.
Many outstanding works of science fiction came from the Eastern Bloc, most notably from authors such as Stanislaw Lem.
Also, if you're into games and have played any installment of the Witcher series, it can be pretty interesting to know that the character was first created for a short story in one of those communism era SF/fantasy zines.
As a matter of fact, all the characters and main plot lines in the Witcher series come from folk tales and pagan legends of the Eastern European Slavic nations, most notably Polish, Croatian and Slovenian (that weird in-game alphabet? 10th century Croatian). So if you're from that part of the world, it's just one big oral history tribute full of inside jokes.
Wow, this really has nothing to do with Venezuela.
Former Yugoslavia, then nominally part of the unaligned block but pretty much part of the Eastern Bloc for all practical purposes. Most famous for the technological marvel that was the Yugo.
