Concept album. Heavy metal with lots of influences from rock and metal acts of the 70s and some doom metal thrown in. Really solid work, IMO, I like what these guys managed to do with this aesthetic. I like it, although not as much as "The Temple in the Underworld" by the same band. The album is in audiofile if you want to check it out.
I think you meant "Tara". It's their most praised album, but I think it falls short comparing it to the two previous albums. I prefer "The Third Storm of Cythraul", to name an album with similar aesthetic and better composition.
Necros Christos - Triune Impurity Rites
slow-to-midpaced Death Metal a-la Autopsy, Goatlord and similar acts. I liked their "Grave Damnation" MCD, but this is just more of the same and without the rotten, dead-like feel of the MCD. Also, it's too long for its own good, maybe this guys' style works better for shorter albums?
