A Finn-Ugric tongue with strong Russian influence. It is likely Karelian.

I’m pretty sure it’s Karelian: it sounds like Finnish but it’s not, and I heard the words “Karjala”.

I agree with Aregnorti and Mut that its a finnic language with russian infuence, but I think it’s veps.

“Terveh, Karjal”, in Karelian, by ensemble “Kantele”, Petrozavodsk.

I agree. Looks like case closed.

Metoo. But they make it sound almost Russian.

The answer is Karelian (Karjalan kieli), a Finno-Ugric language spoken mainly in the Russian Republic of Karelia, and also in Finland.
