Man, I've been on a folk metal trip for the past few years ever since I figured out how to make custom channels on Pandora. I used to just listen to one I'd seed every pretty much everything I'd listen to, so it was a mess of genres and tones. It's pretty jarring to go from The Grateful Dead to Cradle of Filth.

But then I'd seed channels with only one band and see what similar things it'd play. Before long I had a folk metal channel playing things like Tempest, Heidevolk, Tyr, Alestorm, Turisas, Cruachan, so on and so fourth. A lot of it is in languages I don't even recognize. Like there's one band, Eluveitie, who sing in the dead language Gaulish.

I know and listen to most of those, but not familiar with Cruachan or Eluveitie. Thanks for something knew

Recently I was in a cathedral with my wife and we heard what sounded like medieval hymns being sung in a side chamber. We entered and on the other side of the room was some guy sitting in the shadows singing, with all those amazing acoustics bouncing his voice all around the place. And then periodically he would use Tuvan throat singing techniques to throw overtones into his throat. I wish I had had some way to record it.

Saw Altan Urag in Ulaanbaatar with Pleaides about 9 years ago and have been a fan or theirs ever since. Their tunes are part of the soundtrack to the Netflix series Marco Polo I think.
