By definition, deathcore is a hybrid of metalcore and death metal. Deathcore bands typically sound like deathgrind bands with a heavy influence from modern metalcore with frequently used staccato, syncopated open-note breakdowns and metalcore screams. Bands such as Job For A Cowboy and Suicide Silence laid out the blueprints for the genre and spawned many other copycat bands. Antagony, The Red Chord, Despised Icon and a few other bands also helped to popularize the genre. Like metalcore and nu metal, deathcore bands have received heavy criticism for supposed trendiness, lack of skill, and/or differences from “real” heavy metal bands/genres causing many bands to change to a pure death metal sound (Job For A Cowboy/Annotations Of An Autopsy) or a purely metalcore sound (Bring Me The Horizon).
