Welcome to the territory created by Blood, Impetigo, and Repulsion where grindcore takes on darker themes, outside of the daylight world of politics and personal sentiment, seeming to pursue more of the occult vein of death metal. Abatuar sounds like early Napalm Death, Blood, and Total Death era Darkthrone blended.
Very much in the grindcore style as far as technique, Abatuar borrows heavily from Blood and Repulsion for riffing and gathers up the cinematic introductions and transitions of Impetigo, but adds a musicality that keeps parts consistent with one another in maintaining and developing a mood.
Musically mostly chromatic with a few melodic intervals scattered about, Abatuar suffers from too much influence of vocals, but derives its power from the sensible assembly of riffs into a discernible narrative. This pushes it, like later Napalm Death, into the more complex territory of death metal thematically and gives it an aura of obscurity.
