Crust punk is a form of hardcore punk that was heavily influenced by anarcho-punk bands such as Crass or Aus-Rotten. Musically, it mixes elements of metal and is characterized by its heavy and dirty sound. It is normally fast tempo’d and the vocals are usually screamed, shrieked or growled. Lyrically, songs of this genre are typically political in nature.
Some notable bands of this genre include Filth, Amebix, Nausea and Doom.
