I'm not good with genre's so I have no idea what to class Black Dahlia Murder as but...it can simply be called awesome. Unhallowed is a very good album which shows the true intensity and heaviness which can be achieved. Black Dahlia Murder mix a lot of styles into the music, they could be called death or deathcore...who knows what genre they are. All i know is, the music is great. It's heavy with powerful rough vocals and amazing musicians. This is an album which you can appreciate for the sheer heaviness, or the actual skill and complexity of it.
