Thrashcore is often confused with crossover thrash and sometimes thrash metal. Further confusion is added by the fact that many crossover bands, such as D.R.I., began as influential thrashcore bands. Throughout the '80s, the term "thrash" was in use as a synonym for hardcore punk. It eventually came to be used for the faster, more intense style of hardcore punk. The term thrashcore is of recent vintage but dates from at least 1993. The "-core" suffix is necessary to distinguish it from the thrash metal scene, which is also referred to as "thrash" by fans. Still more confusingly, the term "thrashcore" is occasionally used by the music press to refer to thrash metal-inflected metalcore.
History
Origins
Just as hardcore punk groups distinguished themselves from their punk rock predecessors by their greater intensity and aggression, thrashcore groups sought to play at breakneck tempos that would radicalize the innovations of hardcore. Early American thrashcore groups included Cryptic Slaughter, D.R.I., HYPE, Septic Death and Siege. The British Electro Hippies, the Dutch Lärm, the Italian Raw Power, and the Japanese S.O.B. also practiced important examples of the style. Some of Negative Approach's later work was influential on the scene.
Powerviolence
The powerviolence scene grew out of thrashcore as an American counterpart to the British grindcore scene, which had emerged from crust punk, with bands such as Septic Death, Infest and Siege being the first to move towards the style. Powerviolence groups saw themselves as distinct from grindcore because of the increasing proximity of grindcore groups to the death metal being performed in Florida, Sweden, and Brazil. Powerviolence groups wished to avoid the association with heavy metal music and culture that crossover thrash, thrash metal, and grindcore had made, while also incorporating "tempo changes with droney and sludgey down tempo parts". As well as from thrashcore, powerviolence groups also took inspiration from crust punk, and eventually from noise music. Main groups associated with powerviolence included No Comment, Hellnation, Man Is The Bastard, Crossed Out, Charles Bronson, Spazz and Rorschach.
Grindcore
Thrashcore groups such as S.O.B., Cryptic Slaughter, Siege and Deep Wound were major influences on early grindcore acts such as Napalm Death, Carcass and Repulsion, however grindcore is considered to be more metallic, due to its influence from crust punk.
Thrashcore revival
The '90s saw a revival of the thrashcore style, as groups that had previously been associated with powerviolence or grindcore began to explore their debt to this earlier form of extreme rock music. This was sometimes referred to as "bandanna thrash", in reference to the headgear preferred by many of the performers. Prominent '90s thrashcore groups included Refused, Code 13, MK-ULTRA, Guyana Punch Line, What Happens Next? and R.A.M.B.O., Vitamin X, Vivisick, and Voorhees. These groups sometimes felt a greater association with other elements of '80s hardcore punk, such as straight edge, anarcho-punk, youth crew, or crust punk, than most initial thrashcore groups did.
