DIABOLOGY connect four songs through threats that consume people on Demons and Parasites, their forthcoming EP due February 12, 2027, through Dissonant Hymns Records. The Los Angeles death-thrash band pairs three new songs with a re-recording of a live staple from its 2020 debut, Nobody Believes Me.
“All of the songs on the EP deal with evil things (demons) that feed on people and drain them in different ways,” the band explains. The title comes from the chorus of opening track “Them!,” which draws inspiration from the B-horror movie of the same name to imagine AI bringing about human extinction through killer robots. Sweeping leads and thrash riffs accompany clean and harsh vocals.
“Lethe” connects the band's earlier material with its newer direction. A thrash-led introduction gives way to tremolo picking and blast beats with a black-metal edge. Its Greek mythology reference supplies a framework for themes of addiction, substance abuse and lost identity: the river Lethe was said to erase the memories and identity of those who entered it. The band describes the “feeling of addiction, of being so submerged in something that you lose yourself.”
On “Strix,” the narrative follows a man tormented by a creature of ill omen and violence from mythology and folklore. “The song specifically centers around the protagonist’s increasing paranoia, believing the Strix is constantly stalking him and waiting to attack.” Its musical foundation draws on 1980s thrash, with a DEATH-inspired progressive bridge and a sludgy final chorus that moves to a lower key.
Closing track “Seed of the Prophet (2026)” revisits “Seed of the Prophet” from Nobody Believes Me. A staple of DIABOLOGY's live performances, the song returns with harmonized guitar lines, additional instrumental layers and an expanded outro featuring dueling guitar solos.
“We recorded the two guitar solos simultaneously to capture the real time chemistry between us and to give the tracks a more organic push-pull, call and response sort of feel,” the band says. The lyrics address religious oppression and draw inspiration from the 2013 video game BioShock Infinite, including its depiction of a Christian cult floating above the world in the clouds.
Charles Elliott produced, mixed and mastered Demons and Parasites. Recording took place at Tastemaker Audio, and Anditya Dita (Poison Project) created the cover artwork.
The EP follows lineup changes and further development of DIABOLOGY's sound after the sophomore album Father of Serpents. Rooted in thrash, the band has incorporated death, groove, black and doom metal influences, combining modern metal's brutality and technicality with classic thrash's melody and energy within the Los Angeles metal scene.
The current lineup comprises Jesse Bergen on vocals and guitar, Bradley Irving on guitar, Vikram Sinha on bass and backing vocals, and Roan Quirarte on drums.
DIABOLOGY released Nobody Believes Me in 2020 through its own Dissonant Hymns Records label, drawing international attention. Father of Serpents followed in fall 2022 on the same label. Dave Kaminsky (STONE HEALER, FIRES IN THE DISTANCE) produced that album, with mastering by Ryan Williams (THE BLACK DAHLIA MURDER, Metal Blade Records); it received coverage from Metal Injection, No Clean Singing and Knotfest. The standalone single “The Last of All Kings” arrived in 2025.
