Album Review
Drain of Impurity - The Dark Ascension of the Supreme Prometheus Gods

Hey folks, how’s it going? My life has been going downhill lately, and I try to dedicate every moment I manage to stay on my feet to our local metal scene. Anyway, ifenim, the topic of today is Ankara-based brutal/slamming death metal band Drain of Impurity’s nine-track album “The Dark Ascension Of The Supreme Prometheus Gods”.
From a musical standpoint, we’re dealing with an extremely extreme death metal release.

The album sits somewhere between Brutal Death Metal and Slamming Brutal Death Metal, with intensity, weight, and sheer crushing force taking precedence over technical flashiness. Low-tuned and extremely thick tones are employed throughout. The riffs generally swing between fast tremolo passages and heavy “slam” sections. Melodic elements are kept to a minimum, with dissonance and chromatic transitions preferred for atmosphere building. This approach sits close to the line of bands like Cenotaph, Devourment, and Disgorge. (And of course, the BATU ÇETİN factor).
On drums we have Berk (Shrine of Denial, Konatus), with constant blast beat usage immediately standing out. There are sharp transitions between fast passages and groove-oriented slam sections. Here, the drummer’s role is built around increasing density rather than technical display. And yes, we wrote Batu Çetin in parentheses earlier—but now, onto the main event. The vocals on the album follow a typical brutal death metal approach, delivering deep guttural growls and, at times, more suffocating “gurgling” vocals, presenting us with a Batu Çetin classic where vocals are used less as words and more as a rhythmic, aggressive instrument. In total, the album offers 28 minutes of brutal/slamming death metal, showing that it avoids unnecessary repetition, keeps its ideas short and dense, and aims to keep the listener under constant pressure.
Looking at the album’s themes, as can already be inferred from the track titles, it points toward cosmic horror, biological mutation, infection, and cosmic destruction. Tracks such as “Promethean Genetic Vaults”, “Planetary Scale Infection”, and “Biosphere Becomes The Swarm” push the album beyond classic gore themes, steering it toward sci-fi-adjacent concepts like cosmic horror, transhumanism, evolutionary deformation, and the biological transformation of humanity. Visually, the artwork also supports the album strongly. The cover created by Rudi Yanto, with its tones, colors, and the universe it builds, looks extremely powerful.
Built on atmospheric brutality rather than technical showmanship, crushing riffs, and themes of cosmic/biological horror, this album stands very close to an international standard within the brutal death metal world coming out of Turkey. Compared to their previous releases, I would say this is their strongest work in terms of production and structure. Anyone who appreciates the classic Ankara death metal line (Ceno is a cornerstone of death metal!), plus the collaboration of Batu Çetin + Berk Köktürk, should not miss this.
