Powerviolence

Powerviolence (sometimes written as power violence) is a chaotic and fast subgenre of hardcore punk which 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 and grindcore. Like its predecessors, it is usually socio-politically charged and iconoclastic.
