Uneasy listening. Aural autoflagellation. Noisy drone a la Gnaw their Tongues, though, as evidenced by the non-burning churches on the sleeve (look closely, they aren't) , metal is not the starting point. The result is punishing nonetheless, especially track 1. Normally not my cup of tea/chalice of blood, but the medieval chant lends it some direction and, at times, a soothing quality.
Many tracks have that same soft spoken timbre that I love in Glenn Gould's 1962 recording of the Art of the Fugue. There is actually quite a bit more of it, since no one is trying to make something that is evidently not a harpsichord sound as one. -Someone is trying to make what's not(?) a Minimoog sound as one on track 4 though.
