Blurry vodka infused howlings expressing the deep soulful world of the cannibal finno ugric tribesmen.
And that isn't just Tchaikovsky. Russian music is either the clown commie shit for workers and peasants (i.e. Sviridov), or these church howlings. If the Russian music wont turn you into a russophobe, then you're a honorary snownigger. I'm personally not a fan of rap either, but let's be honest, africans have the sense of rhythm. Can't say that about Russians.
