Rock music was banned in USSR, and it was literally underground, people played it despite the risk being arrested and jailed. Primus was one of such bands, and here is the song I loved a lot back to then. It's about Russian warriors killed in one of those medieval battles and called Mourning Song.
Exhausted steppe is blackened by ash.
The night's grim silent is waiting.
There, behind a barrow where the day was burning out
I laid pierced with someone's sword.
