Deathcore is a fusion of musical styles that combines elements of Death Metal with elements of Metalcore or Hardcore Punk, or both. It is defined by an “excessive” use of Death Metal riffs and the use of Metalcore breakdowns.
Deathcore appears to be most prominent within the southwestern United States, especially in Arizona and inland southern California (most notably Coachella Valley), home to many notable bands and festivals.

Death Metal bands such as Suffocation, Dying Fetus, Devourment and Internal Bleeding are credited as predecessors of Deathcore through their use of Hardcore breakdowns and influences. Deathcore began in the early 2000s, with older bands like Antagony, Despised Icon and The Acacia Strain emerging at the time.
The genre expanded in the mid-to-late 2000s with the emergence of bands such as Through the Eyes of the Dead, Bring Me the Horizon, Suicide Silence, Carnifex, Job for a Cowboy, Chelsea Grin, As Blood Runs Black and Whitechapel. In the mid-to-late 2000s, Deathcore became one of the most popular genres in Heavy Metal, with the success of bands such as Bring Me the Horizon, Suicide Silence, Job for a Cowboy, Whitechapel and Carnifex.
In the 2010s, Deathcore bands emerged that fused Deathcore with other genres. This included bands like Emmure and Attila fusing Deathcore with Nu Metal and bands like Veil of Maya and Born of Osiris fusing Deathcore with progressive Metal or Djent. Deathcore has received criticism from fans of Heavy Metal music, generally for its frequent use of breakdowns. Some musicians of the style even rejected the Deathcore label.

Traditional gutturals and growls are common, clean vocals are very rare, and most bands rarely use them; they are present only on certain occasions in selected songs, such as “All Shall Perish” (in the song “Awaken the Dreamers”) and Oceano (in the song “Incisions”). Low growls and high-pitched screams are common types of vocals in Deathcore. Some other techniques used by Deathcore vocalists include what is known as “pig squeal”.

Fusion with other genres
Several Deathcore bands have experimented with other genres in their music as influences over time. Emmure has been credited as being heavily influenced by Nu-Metal and has been described as “the new Limp Bizkit”. Suicide Silence’s 2011 album The Black Crown is a genre album with some Nu-Metal influences. Other examples of bands inspired by Nu Metal include the later material of Here Comes the Kraken.
In the early 2010s, Deathcore bands that combined the style with genres such as Djent and Progressive Metal also began gaining popularity in the underground. Veil of Maya, Born of Osiris, and After the Burial are examples of bands that combine Djent or Progressive Metal. Some bands, such as Make Them Suffer and Winds of Plague, mix the style with symphonic/classical elements. Betraying the Martyrs is known for “tempering the punishing brutality of Deathcore with melodic flourishes taken from Symphonic and Progressive Metal, giving it a theatricality that looks distinctly European


Deathcore has been criticized and belittled, especially by longtime fans of other Heavy Metal subgenres. The reason for this is often the fusion of Death Metal with Metalcore and the use of breakdowns.

Furthermore, members of certain Deathcore bands do not like to be labelled this way. In an interview with Justin Longshore of the band Through the Eyes of the Dead on the subject, he said, “You know, I hate that term. I know we’ve been labelled that, but I think there’s a lot more. Our music is better than just a mix of Death Metal and Hardcore, even though we incorporate those elements into our music. To me, it feels like it’s just the new, new thing that kids are following.”

In November 2013, Terrorizer wrote, “The term ‘Deathcore’ and such is generally seen as a dirty word in Metal circles” – When interviewing lead singer Bryce Lucien of the Texas-based Metal band Seeker. Lucien then declared:
“Much like what Metalcore became in the mid-2000s, Deathcore is an oft-maligned term that can instantly diminish a band’s credibility. What once conjured up images of ridiculously brutal and unapologetic bands like Ion Dissonance and The Red Chord now brings to mind bands full of twenty-somethings with their teeth in their throats, matching black t-shirts and desperately trying to look tough as they jump in synchronization on the stage.
On the other hand, there seem to be bands that seem happier and less worried about being described as Deathcore.

Scott Lewis of the San Diego-based band Carnifex began, “We’re not one of those bands trying to escape this flag. I know a lot of people try to act like they have a big problem with it, but if you listen to their music, they are very Deathcore’. I know there’s a lot of resentment towards Deathcore and younger kind of bands.”
Additionally, in a 2012 interview, former Chelsea Grin guitarist Jake Harmond said, “Everyone likes to bang their jaw and express their own opinion about how ’embarrassing’ it is to be in a band that can be called ‘Deathcore’, but we honestly never cared.
