The album mostly seems to be inspired by the cold and haunting Scandinavian black metal. Many of those ancient bands also come to mind while I listen to songs like 'Hung be the Heavens in Black' or 'The Discrucified'. The latter is also my favorite song on this album, an epic piece of slow but intense music. That being said, yes, there are heaps of slow passages on this album, each more crushing than the other one.
Obviously, being old school black metal inspired, you can also expect plenty of blast beats driven tunes and fierce riffs that will slowly grind your eardrums. I'm 666 percent sure that this stuff will get a lot of old (and new) school extremophiles to bang their head. There is something incredibly catchy about this music, not in a poppy kind of way, obviously. It's catchy as in "grabbed by a hook in your throat and dragged down into hell while your spilling blood mixes with the flesh of the damned ones", something like that.
In all, if you want something gruesome, intense, fearsome and brutal, this album surely is your thing. Black metal is not something that often appears in my day-to-day playlists but this album surely will. I suggest you do that same. Everybody needs something to play loud and exorcise their demons. 'Chrst' is such a record.
