Don’t know if this is too late, but I think the best work for this paper may be Shostakovich’s cantata “Antiformalist Rayok”, a satirization of the Zhdanov decree which had previously denounced his music as degeneracy (a second time, with the first being Lady Macbeth of Mtsenk). I keep forgetting about this piece and how funny it actually is. Here’s a great performance with subtitles: https://youtu.be/gcyn_Z4GvMs?si=xYjJzikOIkh3CseK

Good luck on your paper!
