Sellers on discogs are supposed to specify what release of the album theyre listing. Russians typically dont try to hide that its a Russian press (like south americans tend to) so there will be a specific release page for that release that says it was released in Russia.
That line will just randomly be on the release somewhere btw, I've seen Baltic OBI strips, and it on the back of the booklet or inlay. Again, if the cd wasnt originally released in Russia, its probably an unoffical release. My Carnivore cds have goddamn Russian text on the inlay...
