The EP is also Vio-lence's first studio recording to feature a different lineup, with bassist Christian Olde Wolbers and rhythm guitarist Bobby Gustafson replacing Deen Dell and Robb Flynn respectively, and three-fifths of the Eternal Nightmare lineup – lead guitarist Phil Demmel, vocalist Sean Killian and drummer Perry Strickland – remaining.

[3][5][6] A near-reunion of Vio-lence took place at The Midway in San Francisco, California on January 20, 2018, as a benefit concert for frontman Sean Killian, who had recently been diagnosed with stage four liver cirrhosis earlier.

The benefit included performances by the members of Vio-Lence and their Bay Area thrash metal peers Testament, Exodus, Death Angel, Forbidden and Mordred.

[7] Following Demmel's departure from Machine Head and Killian's recovery from his illness, as well as months of speculation of a potential Vio-lence reunion,[8][9] the band announced on January 8, 2019, that their first show in over fifteen years would take place on April 13 at the Metro in Oakland, which would see them perform the Eternal Nightmare album in its entirety.

[10] Initially planned as a one-off show, it sold out shortly after its announcement, resulting in a matinee appearance at the Metro, which took place on the following day.

"[15] In an interview with Exodus frontman Steve "Zetro" Souza on his "Toxic Vault" video channel, Killian said, "Phil and I have talked a couple of times.

"[16] In January 2020, just as the band was preparing to work on new material, it was announced that Ray Vegas had left Vio-lence and he was replaced by former Overkill guitarist Bobby Gustafson; shortly thereafter, longtime bassist Deen Dell had quit the band for personal reasons and was replaced by former Fear Factory bassist Christian Olde Wolbers.
