In early 2022, Sumerian acquired Behemoth Entertainment, a comic book and video game publisher, in order to increase their merchandise options and further expand the brand.

[1] Founded in 2006 in his Venice Beach apartment, Sumerian Records founder Ash Avildsen first released the records Akeldama by The Faceless and For What It's Worth by Stick to Your Guns in order to let people know the label would be dedicated to underground music but also to diversify the genres of the label, as the former falls under deathcore while the latter is typically described as Melodic Hardcore.

[27][28] Sumerian delivered the highest charting alternative radio song for the Smashing Pumpkins in 12+ years for their lead single "Cyr" off their latest album.

[29][30] In 2010, The Grammy Museum at LA Live had a Golden Gods: History of Heavy Metal Exhibit where the original, band sticker-covered Sony Vaio laptop that founder Ash Avildsen started the label on was displayed as a historical item.

[45][46] In 2019, Guitar World listed two Sumerian artists in the top four guitarists of the decade, Tosin Abasi of Animals as Leaders and female solo artist Nita Strauss,[47] who in addition to her solo career and being Alice Cooper's guitarist,[48] also plays the national anthem for the home games for the LA Rams at Sofi Stadium[49] and for WWE,[50] most recently at WrestleMania 37.
