Yes, there is such a thing as Mongolian Folk Metal, and it is being performed by the band Tengger Cavalry. It’s post-Metallica heavy metal combined with Mongolian folk instrumentation, which gives the band a feel and sound something like Kansas or Yes playing heavy metal or Porcupine Tree with more diverse instrumentation. In the five songs I’ve listened to on their new album, Blood Sacrifice Shaman, there aren’t so much vocals as there are vocal stylizations: vocals are being used like another musical instrument. Seriously rocks, well put-together. Check it out. You can stream their entire album on the website linked above.
