Anything Bigg o))) touches is gold. I don't know of any other Nahuan/Aztec or tribal death-doom bands, but Tzompantli is certainly the premier tribal death-doom band. The production has been noticeably upped and there's more traditional instruments and vocals in this full length than in the previous EP. It's heavy, dark, crunchy, and aggressive, while still having that uncomfortable doom air to it. Staple of death-doom right here.
Favorite track: Ohtlatocopailcahualuztli.
