Grindcore is characterized by:
- heavily distorted, down-tuned guitars, with crust punk-influenced riffing,
- hardcore punk and thrash metal drumming, with many bands focusing on blast beats,
- short songs, rarely lasting more than two minutes and often seconds long,
- vocals which consist of growls and higher-pitched screams, similar to those found in black metal or hardcore punk,
- lyrical concept ranging from social and political issues to gore and humor.
