Månegarm

I could say I'm surprised that such an excelent band still doesn't have its own thread, but it's not really all that surprising. I don't think there's any doubt in fact that Manegarm is one of the most underrated bands in the whole folk and viking metal scene.
For those who don't know them, Manegarm were formed in 1995, initially as a Black Metal band, with goal to play as fast and primitive metal as possible. Yet, starting with their third album (Dödsfärd), they switched into a more melodic form, taking the shape of a folk-influenced Viking Metal band. As far as similarities go, I think today they would be best described as something in-between Thyrfing and Ensiferum.

As I already insinuated, the music they play is excellent. Their songs are really varied and usually pretty heavy, while the atmosphere they build up, dark and epic. The vocals range from clear singing (here both male and female) to harsher forms and finally death growls.
Some songs can be downloaded from their website: http://www.manegarm.com/ (including a track from their latest album, which comes out at the end of this month).

Asides getting people to know about this band, I would also like to know what other Metalstormers think about them
