Powerviolence

Powerviolence (sometimes written as power violence) is a raw and dissonant subgenre of hardcore punk. The style is closely related to thrashcore and grindcore. In contrast with grindcore, which is a "crossover" idiom containing musical aspects of heavy metal, powerviolence is just an augmentation of the most challenging qualities of hardcore punk; like its predecessor, it is usually socio-politically charged and iconoclastic.
