Hardcore Punk

Hardcore punk is a subgenre of punk rock that originated in North America and the UK in the late 1970s. The new sound was generally thicker, heavier and faster than earlier punk rock.[1] The songs are usually short, fast, and loud, covering topics such as politics, personal freedom, violence, social alienation, straight edge, veganism and vegetarianism, war, and the hardcore subculture itself.[2][3][4]

Hardcore spawned several fusion genres and subgenres, some of which had mainstream success, such as melodic hardcore, metalcore, post-hardcore, sludge metal and thrash metal
