Metalcore

Metalcore is a broadly defined fusion genre combining elements of heavy metal and hardcore punk, originating in the 1990s United States and becoming popular in the 2000s. Metalcore typically has aggressive verses and melodic choruses, combined with slow, intense passages called breakdowns. Other defining traits are low-tuned, percussive guitar riffs, double bass drumming, and highly polished production. Vocalists typically switch between clean vocals (melodic, emotional singing) and harsh vocals (including shouting and screaming). Lyrics are often personal, introspective and emotive. It is debated whether metalcore is a subgenre of metal and hardcore, or a genre of its own. Many metalheads do not regard metalcore as a heavy metal subgenre.

In the late 1980s to early 1990s, pioneering bands were founded such as Integrity, Earth Crisis and Converge, whose hardcore punk-leaning style is sometimes referred to as metallic hardcore. These bands took influence from a range of styles and genres such as hardcore punk, thrash metal and death metal. During the decade, the genre diversified, with Converge, the Dillinger Escape Plan, Botch and Coalesce pioneering mathcore, while Overcast, Shadows Fall and Darkest Hour merged the genre with melodic death metal to create melodic metalcore.
