Death metal
Death metal, in particular, is associated with growled vocals. Death metal, which tends to be darker and more morbid than thrash metal, features vocals that attempt to evoke chaos and misery by being "usually very deep, guttural, and unintelligible." Natalie Purcell notes, "Although the vast majority of death metal bands use very low, beast-like, almost indiscernible growls as vocals, many also have high and screechy or operatic vocals, or simply deep and forcefully sung vocals."
