This is a great thread idea that's getting no love. So, I'll pimp something that I expect exactly zero people to like.
I discovered this band called Tenochtitlan. They're from Russia, and the write songs about the ancient Aztec, Mayan, and Inca civilizations. The lyrics are in Russian and broken Mayan and Aztec. The song titles are mostly in Aztec.
They play a sort of atmospheric/ambient tranquil jungle music that really evokes South America, and they mix that with elements of doom metal. It's weird fun stuff that's worth a listen, I guess...
...especially since you can download both of their albums, "Chac Och-Ut," and "Epoch of the Five Suns" for free(!) @
