The first styles of Grindcore emerged as the stylic continuance of Crust Punk, and Crust Punk is a sub-genre of Hardcore Punk. It’s almost like a family tree, if you can picture it that way. Think of it like, Hardcore Punk, and Thrash Metal get married, and have a baby. Their baby is Anarcho-Punk. Anarcho-Punk, and Hardcore Punk have incestual sex, and spawn Crust Punk. Afterwards, Crust Punk runs off, freaks out, and marries Black Metal, but cheats on Black Metal with Hardcore Punk, and spawns Grindcore! Yes, it’s a little round-a-bout and kind of sick, but, so is the music industry in general. Grindcore contains influences from all these genres and subgenres; the shrieking, high pitch vocals of Black Metal, with the musical styles of Hardcore Punk, Crust Punk, and Thrash Metal.
Some of the most notable bands from the Grindcore genre are bands from the early Grindcore compilation album done by the Earache Records label, Grind Crusher; Morbid Angel, Repulsion, Carcass, Godflesh, Terrorizer, Hellbastard, Carnage, Naked City, Filthy Christians, Old Lady Drivers, Intense Degree, Sore Throat, Napalm Death, Entombed, Nocturnus, Bolt Thrower, Lawnmower Deth, Cadaver, Sweet Tooth, Mighty Force – Thrashing a Dead House, Spazztic Blurr, Heresy, and Unseen Terror.
The majority of Grindcore’s influence came from the UK and American hardcore punk and thrash metal scene, mainly from bands like the UK’s Discharge and Amebix, and America’s Siege, Larm, and Repulsion. And, because Grindcore has been a phenomenally successful underground movement, there are several subgenres. Cybergrind; a subgenre fusion of Grindcore and extreme electronica, for example, bands like Genghis Tron. Crustgrind, is a subgenre of Grindcore that is more Crust Punk than Grindcore, such as Disrupt, Phobia, and Extreme Noise Terror. Then there’s Deathgrind, which is a subgenre featuring a fusion of Grindcore and Death Metal, band examples such as AssÃ¼ck, Brutal Truth, Cattle Decapitation, Cephalic Carnage, Napalm Death, and Nasum.
Goregrind is a subgenre of Grindcore so named for its lyrical gore themes, with band examples like Carcass and Regurgitate. Noisegrind is a subgenre, adequately named for its focus on the speed and amount of distorted noise, with examples like Anal Cunt, Gore Beyond Necropsy, Fear of God, and The Gerogerigegege. Pornogrind speaks for itself; the subgenre of Grindcore is named for its lyrical content as well, and features bands such as GUT and early Cock and Ball Torture, that have themes of extreme sexual nature in their lyrical content.
