Founded in 2001, UNMERCIFUL released its debut, Unmercifully Beaten, in 2006. With intensive tour runs from 2006 through 2009 with the likes of Cannibal Corpse, Dying Fetus, Necrophagist, Decrepit Birth, Cryptopsy, and more, the band went through various personnel changes before deciding to disband in 2009. What started out as just a reunion show in 2012, quickly returned the band to working status. With consistent live shows and numerous metal fest appearances, the band released a self-titled demo in 2014 as a first step in the process to completing its first full-length release in nearly a decade. After the abrupt departure of drummer James King, John Longstreth was enlisted to record drums for Ravenous Impulse.
