there's more than one band named Xibalba I've concluded. The tags on that video Seth posted said they're from California. There's another Xibalba from Mexico that play black metal. They sound obviously different.
I cant understand why I think this is good. Its right on the boarder of being something I would hate.
you know, I honestly thought you confused the two bands at first, but I watched this video a few times, and the only thing that really sets this band apart from being a death metal band that I'd enjoy is the awful vocals.
