Hardcore
is an aggressive punk rock subgenre that emerged in the late 1970s, known for its fast tempos, intense energy, and raw, shouted vocals. With short, powerful songs, it channels themes of rebellion, social issues, and personal struggle. Hardcore emphasizes DIY ethics and community, often influencing both punk and metal. Key bands like Black Flag, Minor Threat, and Bad Brains helped define its uncompromising, confrontational sound and ethos.
