Anyway, on to the music because that's something very interesting. Of course, it's black metal, meaning that you'll get a load of fierce, distorted guitars, blast-beats and haunted screams but there's so much more going on here. There a very strong emphasis on creating a dark, gruesome atmosphere, hence the use of synths. Furthermore there seem to be some influences beyond the black metal scene, such as darkwave for instance, or even harsh noise.
Those elements give the otherwise quite thrashy and chaotic music a huge plus in my eyes, or ears. On one hand it adds a melodic aspect but on the other hand, which is the case in 'Prayer - The Fear' it adds a highly hypnotic feel. The noise aspect, is audible mainly in the harsh, bleak sound, created mostly by the production quality. That makes 'Where Hollowness Dwells' a great album, painful, angsty and downright malignant.
