Thrashcore

Thrashcore (also known as fastcore) is a fast-tempo subgenre of hardcore punk that emerged in the early 1980s. Thrashcore is essentially sped-up hardcore, adopting a slightly more extreme style by means of its vocals, dissonance, and occasional use of blast beats. Songs are usually very brief, and thrashcore is in many ways a less dissonant, minimally metallic forerunner of grindcore. The genre is sometimes associated with the skateboarder subculture.
