In my endless, and most of the time fruitless, search for asian folk i stumbled upon this band. They have one album as far as i know, although the production sucks, the typical korean folk elements are there and sound great. I cant tell much else, since i don't speak korean. So if you are also search for asian folk, check this one.

Well, got impressed by your thread because of "folk". But to be honest, they are good but not much Folk or ASIAN folk.

If there is more Asian metal bands recommend me.

Yes, i know they are more goth than folk.

Also not Goth but Symphonic with some folk. Shame there isn't really any "real" Asian Folk Metal band, the Chinese Folk Metal band Empylver also has just a few Chinese Folk influences and the rest is European.
