I do not listen to Spotify, so can't link to anything there....

Look for a band called The HU. The most popular song is Wolf Totem. They are a Mongolian band that uses 'throat singing'. I guess some would call them heavy metal, but I don't. I don't know what genre they are. Deep instruments, base, some flute, deep vocals, a bit dark. Interesting enough for me to buy one CD. Probably not a second.
