AKA: “Tuvan throat-singing.” I think it’s one of the most ‘metal’ things around, and I’ve been a fan of Laibach since their first album came out in the US in the mid 1980s. The lead singer for Laibach doesn’t really do polyphonic overtones, but it’s a similar sound.
I’m a fan of The Hu, who get good mileage out of throat-singing though, to be honest, the vocalist doesn’t have a lot of range and sophistication in the overtones he gets. That’s fine for Make Mongolia Great Again types, but when it’s approached in a disciplined manner, you can get some amazing results.

Her delivery is really delightful, too – I can’t tell how much of it is her accent or just how she explains things, but she comes off as very, very, dry with a whiff of irony. When someone does careful archeology regarding how our bodies do something, and explains it, it’s always fascinating to me. It takes a lot of analysis and self-awareness to figure out what’s going on, and then formulate an explanation that is comprehensible to another – you can’t just say “it’s an internal thing, oh, I dunno, you do it with your throat.”
If you want something a bit less dry, here’s The Hu:
