A sub-genre that describes deathcore bands who are signed to Sumerian Records or bands who have stylistic similarities to these bands. The genre is a mix of technical death metal, deathcore and mathcore. The derivation of the word is unknown, though the most typically accredited source is MetalSucks.net. The website coined the word in early May 2009 when they were discussing the latest Born of Osiris release, one of Sumerian Records's most well-recognized and longest-tenured bands.
"Dude, have you heard the new Veil Of Maya album?"
"Hell yeah man, VOM is the best Sumeriancore band."
