Looking for really obscure instruments that can be considered traditional in a certain country. For example, the er-hu is a traditional chinese instrument from China. I believe there are plenty of it used in bands such as Eluveitie, Negura Bunget, Orphaned Land.
Are there any that uses traditional African instruments?
Do note that i am not looking for bands that uses saxophone, trumpet.

Take a look at Senmuth, He uses plenty of tribal/ethnical tunes. If you want African stuff, check out the album Aethiopia.

The likes of Waylander, Cruachan, Folkearth and Folkodia use Tin Whistles, if that what you are interested in?

Sorry for the double post, But just had a brainwave.

Band - Instrument
Darkestrah - Temir-Komuz
In Extremo - Bag Pipes
Alestorm - Keytar
Slartibartfass - Jew's Harp
Тінь Сонця - Bandura

Bagpipes are very common of late, espiecially bagpipe driven band, Skiltron, a fine example.
I'll check the rest. Good call on the tribal elements. Hope there are more to discover

Latvian pagan/black metallers Skyforger occasionally use not only bagpipes, but also the traditional Latvian instrument the kokle, a stringed instrument like a zither.

I also would like to see more African instruments in Metal; I reckon the kora would work rather well.

Nest are well known for their use of the kantele

Tevana 3 are a new band who use an electric kantele instead of an electric guitar -- one of my favorite recent albums.

Gigandhi - Tablas, Didgeridoo, Sarod, Tanpura

Not every song though.

Chthonic. Taiwanese band, they use some sort of traditional instrument that's sort of a one-stringed violin. They also emulate harps and other instruments on keyboard.

Nest are also well known for not playing metal.

Marțolea uses bucium, kaval, mouth harp and wooden flute, apparently. It's a folkish black metal one-man project with some diverse influences. For one thing, the song Ceas Rău sounds like a punk song.

Read opening post.

japanese avant garde metal with traditional flutes (nohkan, shinobue, dengakubue)

Tengger Calvalry from China uses the horse-head fiddle.

Eluvitie doesn't use the erhu.

Well, they're Crust and not exactly Metal but Al Thawra use traditional Middle Eastern instruments. It seems kind of gimmicky, but surprisingly it sounds rather nice.

Learn to read when there is a full stop. Plenty of obscure instruments used in bands like Eluveitie, if you need me to spell it out for you, and obviously they are not from China

are flutes not obscure? in Death Metal? cause Conscious Rot use flutes: http://www.youtube.com/watch?v=m4sT8jsoyIM



what about whistling?!? yes whistling, who the hell has whistling solos? Headrot, that's who: http://www.youtube.com/watch?v=DzprukqDvKQ

Melechesh springs to mind.

Well if you want traditional Chinese instruments Shangren is full of it, I don't know which, theres a bunch of em.

The band put their whole album on youtube. Here's one song http://www.youtube.com/watch?v=RCmjw-PtQj8

God of Shamisen uses shamisen (obviously)

I would also like to second the Tengger Cavalry recommendation. My favorite Asian metal band.
