Philadelphia’s filthiest and finest Progressive Death Metal band returns in full force with their fifth studio album, a labyrinth where the deeper in you go, the more it twists and churns, luring you toward some monstrous final battle.

Five years after their latest album Idol, Philadelphia’s filthiest and finest Progressive Death Metal band Horrendous is finally back with their fifth full-length instalment, titled Ontological Mysterium, a love letter to Death, Atheist and other classics from the late 80’s and early 90’s. Produced, engineered, mixed and mastered by the band’s own Damian Herring at Subterranean Watchtower Studios, and displaying a sick artwork by Alex Brown and Brian Smith, Ontological Mysterium is a labyrinth where the deeper in you go, the more it twists and churns, luring you toward some monstrous final battle, all masterfully brought into being by the aforementioned Damian Herring on vocals and guitars alongside Matt Knox also on vocals and guitars, Alex Kulick on bass, and Jamie Knox on drums.

A Stygian invocation titled The Blaze warms up the listener for the infernal metal attack that’s about to come in Chrysopoeia (The Archaeology of Dawn), a fast and demolishing tune where the riffs by Damian and Matt set fire to the atmosphere spiced up by the song’s demented lyrics (“Immerse me / In jubilant flames / With iridescent tongue / Lick away the skin / Don’t dare be kind / Paralyze me in paraffin / And spark the match”). Then blending the madness and creativity of Mastodon with their own Death Metal vein we have Neon Leviathan, and the result is a crushing tune where Alex steals the spotlight with his metallic, groovy bass punches; followed by Aurora Neoterica, bringing forward two minutes of sheer insanity, progressiveness and atmospheric passages where Jamie and Alex make an amazing duo with their respective beats and bass lines, flowing into the intricate Preterition Hymn, where the quartet once again blasts our ears with their sonic extravaganza, delivering a sick fusion of harsh growls and clean vocals (albeit not as exciting as the rest of the album).

In the wicked Cult of Shaad’oah  we’re treated to more of their lunatic words (“Beat me back but I’ll keep on climbing / When you’re lost in the dreams / Of the dead / And the final sun burns / Oh, the battle begins… / Prepare for brutal ascent”) amidst a fantastic Progressive Death Metal sonority led by the band’s guitar duo’s caustic riffage; whereas switching gears to a darker, heavier sound with a dense atmosphere, it’s time for the cryptic Exeg(en)esis, once again blasting our ears with their chaotic yet extremely melodic riffs, beats and bass lines, or in other words, a weird creation that fits really well in the album, followed by the Progressive Metal-infused title-track Ontological Mysterium, where Horrendous showcase all their insanity and passion for heavy music. Moreover, Jamie is amazing as usual behind his drums while the diversity of vocal styles again reminds me of some of the best songs by Mastodon. Lastly, how about another explosion of Progressive Death Metal to close the album on a high note? That’s what you’ll get in The Death Knell Ringeth, with the whole song sounding very compelling and dynamic, while the guitars by Damian and Matt exhale sheer electricity.

“At this point, we want to wave the Horrendous banner high in a way that we perhaps didn’t around Idol and continue on this path that we’ve forged,” said the band’s talented drummer Jamie Knox. “We are very proud of Ontological Mysterium and what our band has become – it’s almost like we’ve figured out how to make this band work amidst the wildness of adult life. This entity feels worth celebrating and feeding to see where it might take us next.” Hence, go check what the band is up to on Facebook and on Instagram, including their tour dates and plans for the future, and of course go grab a copy of Ontological Mysterium from the Season of Mist webstore, as well as by clicking HERE or HERE, and don’t forget to also stream such demonic album in full on YouTube and on Spotify. Having said all that, what are you waiting for to enter the labyrinth of progressive, technical and extremely heavy Death Metal crafted by Horrendous in their infernal new album?
