Deathcore

Deathcore is an amalgamation of two musical styles: metalcore and death metal.

Characteristics
Deathcore is heavily influenced by modern death metal in its speed, heaviness, and approach to chromatic, heavily palm muted riffing and dissonance. Traditional growls, and screaming are prevalent, and sometimes metalcore yelling or shouting vocals are included. Much of deathcore features breakdowns and melodic riffs common in metalcore.

History
Though an early hybrid of death metal and crossover thrash was practiced by Michigan's Repulsion, New York death metal veterans Suffocation and Maryland's Dying Fetus were among the first death metal groups to make the breakdown a staple in their music. Additionally, the straight edge hardcore group Earth Crisis borrowed a great deal from death metal, as did Converge and Hatebreed. Before the rise of deathcore, bands such as Abscess and Unseen Terror used the term to describe hardcore punk/death metal hybrids. Germany's Blood also released a 1986 demo entitled Deathcore, while another German group, formed in 1987 and related to Blood, used "Deathcore" as a band name.

Deathcore seems to have most prominence within the southwestern United States, especially Arizona and California (most notably the Coachella Valley), which are home to many notable bands and various festivals.
