Grindcore, often shortened to grind, is an evolution of
crust punk, most commonly associated with
death metal, a very different though similarly extreme style of music. Grindcore is characterized by heavily distorted, down-tuned guitars often showing
crust punk-influenced
riffs,
blast beats by drummers, short songs, and a vocal style consisting of
growls and higher-pitched vocals, often similar to those found in
black metal. Lyrical concepts range from social and political issues to gore and horror to humor.
