Powerviolence (Sometimes Written As Power Violence) Is An Extremely Dissonant 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. Like Its Predecessors, It Is Usually Socio-Politically Charged And Iconoclastic.
