Thrashcore

Thrashcore (also known as fastcore) is a fast tempo sub-genre of hardcore punk that emerged in the early 1980s. Thrashcore is essentially sped-up hardcore punk, with bands often using blast beats. Songs can be very brief, and thrashcore is in many ways a less dissonant, less metallic forerunner of grindcore. Like hardcore groups, thrashcore lyrics typically emphasize youthful rebellion or antimilitarism. In some ways, the genre is aligned with skateboarder subculture.
