Well I'm searching for groups that sing in their own language . No English but Icelandic or Faroes language like Tyr . And Scandinavian groups too (in Swedish, Norwegian, Danish) like Fejd .
Thanks for your help .

Månegarm is a swedish Viking metal band that sing in swedish. It seems that you're mainly looking for folk/viking metal band but I do know some metal bands that sing in swedish that aren't folk/viking. Raubtier sing in swedish but they're Industrial Metal, they sound a lot like Rammstein

There's Thyrfing, Otyg, Vintersorg, Finntroll that sing in Swedish.
Myrkgrav, Windir, Einherjer in Norwegian.
Moonsorrow, Korpiklaani, Ajattara(not Pagan metal) in Finnish.

When in Danger or in doubt,
Run in circles, Scream and shout.

Also Enslaved in Norwegian and Svartsot in Danish (I think)

I'd like more Folk than Viking or Black . Thyrfing I know and I like very much but I'd like someone who sings clearly . You know, as if I could understand Tyr if I knew Faroes language !
Vintersorg I don't like very much . Korpiklaani it's really good too .
I'm gonna listen to Sólstafir . Icelandic it's really what I want .
Go on like that .
Thanks !
