Seeping out of the US; Mania play underground Black metal with added elements of, well, pretty much every other filthy, blood-caked underground Metal genre there is.
This is a very varied release, yet none of it sounds out of place and it all fits within the murky template of Black Metal. Combining everything from blackened Grind, to (grim) Post-Metal, to blasting Black, to blackened Doom, to mid-paced attack to…they manage to cover it all and do all of it well. The song Mirror is a great example of this. Within its 8 minutes we have softly-softly Post-Metal, whispered Doom, blasting screaming Black Metal and angelic high vocals. Perfect.
Variety for the sake of it can be a catastrophe but Mania are skilled enough to pull it off effectively. Combining the best of rough-and-ready underground Black with the souring epic melodic atmosphere of Cascadian Black, I find it hard to say enough good things about this album. The atmosphere conjured up on this release is just awe-inspiring. In fact, the only thing I can find to complain about is the length – next time I want more!
One of the best, most accomplished Black metal releases I have heard this year. There is nothing to not like here.
Favourite Track: Portals.
Wonderbox Metal 
This is weird. From the top to bottom. Too much ambient.

I’m a big fan of Daemon Worship’s releases as a general rule. Usually quality album art also.
