Historical roots and influences

The genre was developed during the mid-1980s in the United Kingdom by bands such as Napalm Death and Sore Throat, the name "grindcore" being coined by Napalm Death's drummer, Mick Harris.

"Grindcore came from 'grind', which was the only word I could use to describe Swans after buying their first record in '84. Then with this new hardcore movement that started to really blossom in '85, I thought 'grind' really fit because of the speed so I started to call it grindcore."[1]

Many of the earliest grindcore bands were featured on the Earache Records compilation, Grind Crusher. Swans were an influential American rock, experimental, folk and post-industrial band active from 1982 to 1997, led by singer, songwriter and multi-instrumentalist Michael Gira. ...

The genre, however, is considered a progression of hardcore punk[2] and, for some reviewers, this genre is also influenced by thrash and death metal[3]. Groups such as the UK's Discharge and Amebix and the US-based Siege, Lärm, and Repulsion were influential. Post punk, such as Killing Joke and Joy Division, was also cited as an influence on early Napalm Death, the latter cited on the dvd side to the re-release of Scum.

Many of these early bands were seen by their contemporaries as part of the anarcho-punk/crust punk and hardcore punk scenes, as many anarcho-punk and peace punk bands in England and hardcore punk bands in the United States had already incorporated elements of metal into their music. Many of these early bands were, and still are, obscure. For instance, the thrashcore band Siege only released one do-it-yourself demo, entitled Drop Dead, and Repulsion was posthumously exposed to the world in 1989 through the album Horrified, which was released in Europe through Carcass-owned Necrosis Records, despite having originally been recorded in June of 1986.

Microsongs

One well-known characteristic of grindcore and related genres is the microsong; songs lasting seconds. Clocking in at just over one second long, the Napalm Death song "You Suffer" is often credited as being the shortest song ever. In 2001, the Guinness Book Of World Records awarded Brutal Truth the record for "Shortest Music Video" for 1994's "Collateral Damage." However, others, such as the Cripple Bastards on their demo 94 Flashback di un Massacro and Agoraphobic Nosebleed on their 3" CD/10" LP Altered States of America, have taken this aesthetic to even greater extremes. Altered States of America contains 100 songs, with song length ranging from four seconds to, at most, one minute, adding up to a total play time of 21:44.

Grindcore vocals sounded torturous, ranging from high-pitched shrieks to low, throat-shredding growls and barks; although the lyrics were usually quite verbose, they were very rarely intelligible.
In Napalm Death's hands, grindcore was actually rather arty, a sonic metaphor for the bleakness, violence, and decay of modern society; the group's lyrics were additionally packed with angry social commentary.
Grindcore's blistering intensity was assimilated not only into underground heavy metal, but also into avant-garde and experimental music circles; Japanese noise bands like the Boredoms and Merzbow found it inspiring, and jazz musician John Zorn formed the grindcore-inspired group Painkiller (which featured former Napalm Death drummer Mick Harris).
