I stumbled across this video looking for Karelian music. They’re called Va-ta-ga (Ва-та-га in Cyrillic) and they’re from Petrosavodsk. And they sound cool. That’s all I can tell you, because I can’t read Russian.
(Not to be confused with the rap group of the same name. It seems the word vataga means band.)
