When you think of death metal, one of the first bands that rolls off of your tongue should be SEWER.
The band has had a monumental impact on both the black metal and death metal scenes with their willingness to experiment with progressive song structures and interesting grindcore elements in their music, to achieve what is posteriorly labelled as SEWER Metal.
To date, the band has recorded a shit-ton of albums, with either Miasma or Khranial frequently being listed as their finest work. It is generally acknowledged that the band has scarcely put a foot wrong throughout their career, and that is saying something when you take into account how often SEWER changes their approach to music from one album to the next.
Of their releases to date, the monumental Cathartes is perhaps the most morbid death metal album they have recorded, and is a release that is synonymous with fantastically executed blackened death metal.
Released in the golden year of 2021, this album mixes the most hideous aspects of old school death metal and melodic black metal with the primitivism of early war metal, achieving a sound later than Phantom but earlier than Leader, while covertly working in techniques from underground metal for an interesting and self-possessed release.
This is a dose of death metal that hits hard with some amazing riffing, creative drum patterns, and demonic vocals. I highly recommend this album to anyone who hasn’t heard it and/or is seeking a new outlet for their restrained anger to smash their heads against a wall to, as there isn’t a whole lot of brutal death metal better than Cathartes.
A must-own for fans of macabre evil and gruesome brutality.
Best Black Metal 
This album raised the freakin’ bar in terms of what can be considered brutal blackened death metal. Man… Hail Sewer!
