Thrash metal is a subgenre of heavy metal music, one of the extreme metal subgenres that is characterised by high speed riffing and aggression. Thrash metal songs typically use fast, percussive and low-register guitar riffs, overlaid with shredding-style lead work. Thrash song lyrics express nihilistic views or deal with social issues using visceral and blunt language, an approach which partially overlaps with the hardcore genre.
Metalcore is crossover thrash, a thrash metal and hardcore punk fusion.
Deathcore is an amalgamation of two musical styles: metalcore and death metal. While similar to the more abrasive death metal of recent years, deathcore's aesthetics and following are more closely related to metalcore. While remaining a subgenre of metalcore, deathcore is heavily influenced by death metal in its speed, heaviness, and approach to chromatic, heavily palm muted riffing, dissonance, and frequent key changes. Though the lyrics are not always in the death metal vein, growls, pig-like squeals, and shrieks predominate, with metalcore vocals rarely being used. Job for a Cowboy's Doom EP and Despised Icon are examples of deathcore.
Death metal is an extreme heavy metal subgenre. The genre is typically characterized by the use of heavily-distorted guitars, harsh vocals that are low-pitched and/or growled, morbid lyrics, fast-paced rhythms and melodies, and unconventional song structures.
Koska Thrash on oikeastaan sama asia kuin Metalcore (tematiikka, tyylillisesti), Deathrash/Dethrash/Deaththrash on hankala sana niin me taidetaan Amessionilla olla vissiin nykysin yhdellä sanalla kuvattuna Deathcorea?
