In this video, Dr. Peterson mentions another major piece of Soviet Samizdat. The Master and Margarita.
It’s worth mentioning that the entire book, as a movie, is available in about 10 parts of roughly an hour each on Youtube and is well worth the time to watch.
As an aside, South Park did a great homage to the Master and Margarita in one episode of the show, Season 13, Episode 3, Margaritaville. Its quite funny as a stand alone, but if you have seen The Master and Margarita, its even better.
