It has been defined as a "cluster of metal subgenres characterized by sonic, verbal and visual transgression".  The term usually refers to a more abrasive, harsher, underground, non-commercialized style or sound associated with the speed metal, thrash metal, death metal, black metal and doom metal genres.  With the exception of doom metal, all of these genres are characterized by fast tempos, attesting to their roots in hardcore punk, which has also fused with extreme metal in the forms of crossover thrash, crust punk, grindcore, sludge metal and metalcore.  Though many extreme sub-styles are not very well known to mainstream music fans, extreme metal has influenced an array of musical performers inside and outside heavy metal.
