Napalm Death, I'd start with 'Utopia Banished' Brutal Truth-Need To Control. Misery Index-Retaliate Assuck is killer too.
Good YOU is an oxymoron... oh yeah. Circle Of Dead Children, Pig Destroyer, Intense Hammer Rage, Exhumed (their first is pretty much grind, later stuff is more death metal), Fuck... I'm Dead, Prostitute Disfigurement, Mortician (kinda death/grind), Blood Duster, The Day Everything Became Nothing, Cumchrist... Other than that, I don't really know, I'm gonna be watching this myself
Not all of these are strictly pure grind, but they all rock... Assuck, Pig Destroyer, Neuraxis, Cephalic Carnage, Abaddon Incarnate, Disfear, Prosthetic Cunt, Balatonizer, Fuck... I'm Dead, Catasexual Urge Motivation, WTN, The County Medical Examiners, Napalm Death, Brutal Truth, Extreme Noise Terror, Suppository, Circle Of Dead Children, Papercut Homicide.

Prostitute Disfigurement and Lykathea Aflame are not grind. Ahumado Granujo is hilarious, yet pretty damn good. Circle of Dead Children > everything.
There both brutal death metal. A few more suggestions: Agathocles - Humarrogance Cephalic - Blasted into lunacy Dispised icon - The healing process Bodies in the gears of the apparatus - Simian Hybrid Prototype Repulsion - Horrified Cephalectomy - Eclipsing the dawn Japanische Kampfhörspiele - Hardcore Aus Der Ersten Welt
I hardly like any pure grind. The only grindcore bands I like are (most of these are a hybrid of death and grind): early Carcass early Napalm Death Abaddon Incarnate Pig Destroyer Terrorizer Man Must Die Bowel Stew Corpsefucking Art Assuck Vaginal Jesus Repulsion The Berzerker maybe I am missing some, but I do not listen to much grind.
Brutal Truth is the most solid one I know of. Early Carcass and early Bolt Thrower are worth a look. The Irish band Scald is most certainly worth a look if you're adventurous enough doomsh sludge prog-grind.
Scald are great, but I don't find them to be grind in any way. Their music is for the most part not fast, and they never use blastbeats. To me it sounds more like fucked up, technical, complex sludgy death/half-thrash. Great stuff nonetheless.
Neuraxis sound like melodic death metal to me. A term I hate to use but they do. They are not brutal or regular death metal.
There earlier stuff was brutal death, there newer stuff (truth beyond) is both brutal and melodic. There definately not pure grind and thats for sure!
