Progressive death metal with all sorts of stylistic changes. I normally can't do all death vocals, but the music on this is so friggin' awesome that I hardly notice them.
I used to have 2 of thier albums (Warnaments and something with an odd-sounding title... Yermis Pectis or something...) and I don't remember much about them but I do remember liking them, and I'm VERY picky when it comes to death or black metal.
I like what I hear from this new one, I'll have to check it out more & re-listen to the older albums!
