I like both death and black vocals. Probably black more. Prefer extreme vocals over clean. I like the folk instruments but not too heavy on them. I guess any language is fine.
I like most of what everyone has posted so far. What I don't like is stuff like Tyr, Turisas, and Alestorm. What I do like is stuff like the Windir and Myrkgrav that Draele posted.
Thanks guys!
good info!
I don't disagree with anything mentioned so far (though personally I've never been a big Turisas or Alestorm fan). here's what I'd add:
for Folk/Black:
Mithotyn (if you like their riffs, also check out Falconer, which is the Folk Power Metal band the guitarist started, wanting to go in a different direction)
Thyrfing (their style varies quite a bit from earliest to latest albums, so check out a number of songs)
Eternal Tears of Sorrow (their old albums. Melodic-Death, but like early In Flames they have Scandinavian Folk influences in their riffs)
Wolfchant
Pagan Reign (the only band in this Folk/Black list with a very strong woodwind sound that might take some getting used to)
Taunusheim
Hromovlad
Finsterforst (their recent album was very popular)
Alkonost
Panychida
Menhir
if 'Black' (scare-quoted) is cool with you (i.e., Christians doing Black Metal):
Slechtvalk and Holy Blood are cool
for Folk/Death, Svartsot is an absolute must. Strydegor is another good one. Heathen Foray (from Austria) has a kinda Children of Bodom tech style that's cool, too. And Winterdome has a cool Symphonic Death sound that's a lot tighter than Haggard's style of Symph/Classical Death.
for a Celtic feel: Eluveitie, Suidakra, Mael Mórdha, and the new Bran Barr album.
personally, I'm big on the Belarusian sound right now, which has the same vocal elements as other Slavic Folk Metal, but quite a Thrash influence:
Kamaedzitca and Weeping Twilight have the richest, most developed sound; Gods Tower and Vicious Crusade are clearly precursors to their style, so a little simpler, if you like that.
Litvintroll is very different, bagpipes led.
Dysperium and SIG:AR:TYR are pretty good for Can/US efforts.
Falkenbach, Ensiferum, Månegarm, and XIV Dark Centuries are a good place to see if you develop a taste for pagan vocals, since they vary between Black and clean pagan vox. If you do like them, definitely check out Heidevolk, Grimm (the one from Holland), Vintersorg, Nomans Land, Folkodia, and Isengard.
If you like Månegarm's Thrashy Pagan vox, check out Thronar, Rusich, Hroptatyr, and SatanaKozel. A lot of German and Slavic Folk Black is in a similar vein.
and even if you're not big on clean vox, I still recommend checking out and Kalevala's debut album, and Chur's most recent.
If you like any more Rock-like stuff (generally rhythm guitar and a folk instrument playing lead, and clean vocals), again Chur and Kalevala are great, but so are Svarga (the one from Russia), Schandmaul, Ignis Fatuu, Balkandji, and Nasledie Vagantov.
