Metalcore

is a fusion genre blending the aggression of hardcore punk with the heaviness of metal. Characterized by breakdowns, melodic riffs, and harsh vocals, it often incorporates clean singing and elements from melodic death metal. Emerging in the 1990s, bands like Killswitch Engage and Converge helped define its sound. Modern metalcore explores diverse influences, evolving into subgenres that include progressive, technical, and experimental styles.
