Grinding Death, a la Repulsion (ESP Horizon II and Kemper on this track)

If you are willing to take a little creative input from and old school guy that has been listening to grind and death since the early 90s, it would be this:
Don't try so hard. Old Napalm, Assuck, Carcass, etc are bad recordings because it was all the bands had at the time. Their releases are crusty AF, not because they wanted them to be that way, but because they didn't have the money for better production. A lot of modern grind influenced bands seem to go out of their way to purposefully make their production sound bad. Nails is a great\terrible example of this. It is clear on You Will Never Be One of Us that they took a fairly decent recording and put it through a distressor plug-in to make it sound like distorted racket. Napalm has been doing this with Barney's voice on the last few releases to cover the changes in his vocal style.
A certain amount of grit is expected in a grind related release, a la Venomous Concept, but don't go out of your way to make it sound trashed. My personal preference would be to dial back the distortion on the vocals a little. That level of constant static will fatigue the listener's ear.
My $0.02; take it or level it.
