Unholy Black Pentagram is a new occult Black Metal band from Badalona (Barcelona), Catalonia, Spain.
They emerged publicly in 2026 with a debut demo, ‘Desecrating the Altars of Purity: Unholy Rituals of the Goatlord’, which was released through WolfKult Religion, containing two bonus tracks.
Unholy Black Pentagram is made up of band members gaining experience in the likes of Nigromancer, Under The Moon, Crucification, Messe De Minuit, Stygian Storm, Atonement, Harvest Of Grief, Trollcave, Nagyszeben and Körgull the Exterminator, so you could rightfully speak of a group of seasoned musicians.
It’s this type of musical experience that is immediately shown here.
For a first demo, this is an incredibly impressive recording on which the band has very successfully captured the Black Metal spirit of the late eighties and early nineties with a mature sound.
Think of a combination of Samael, combined with the eerie occult Black Metal antics from bands such as Varathron, Rotting Christ and Necromantia.
Add to that the first two records of Mystifier, and the doomier antics of Goatlord.
In the opening tracks of the demo, Unholy Black Pentagram lean into mid‑paced, no‑frills riffing wrapped in an eerily convincing haze of ritualistic keyboards, the kind of atmosphere that instantly pulls you back to the formative years of occult Black Metal. Dungeon synth before the genre/name was even coined. The vocals, a series of deep, growling cavernous growls, reinforce that doom‑laden aura, giving the slower passages a weight that feels genuinely archaic.
Although the demo largely thrives in this measured, brooding tempo, it isn’t confined to it. When the band accelerates, the music becomes rougher, more primitive, channeling the Goatlord‑like murk and flashes of barbaric violence reminiscent of early Beherit or even Archgoat.
It’s this blend, the deceptively simple structures, the uncanny, incense‑thick atmosphere, and the tension between ritualistic invocation and feral eruption, that makes ‘Desecrating the Altars of Purity: Unholy Rituals for the Goatlord’ such a compelling first statement. Unholy Black Pentagram already show a firm grasp of that late‑80s/early‑90s occult Black Metal spirit that flourished outside Scandinavia, and they’re clearly a band worth watching.
In short: if you crave archaic atmospheres reminiscent of Samael, Varathron, Rotting Christ, Necromantia, Mystifier, Goatlord with the occasional barbaric faster passages evoking Beherit or Archgoat, Unholy Black Pentagram are mandatory!
The cassette is said to be limited to a mere 50 copies.
