Weakling - Dead as Dreams
edit: Necros Christos are likely one of the most evil sounding bands in metal right now, and are one of the best at doing that kind of thing. I still haven't really gotten into that album as much as I'd like to, but it seems like a grower and I really appreciated its sound when I first heard it. It isn't something I'd like to hear all the time, but it is really effective at its atmosphere.
