Grindcore is an extreme form of heavy metal, related to death metal, and pioneered by the British band Napalm Death in the early 1980s. Since then, the grind sound has evolved but is still recognisable by its intense blast-beat sound, grinding guitars (hence the name), and very short songs (at least one Napalm Death song is less than a second long.)
