Bandcamp You’re four minutes into “Black Mass” before the trio settles. Up until that point the song has been working a slow build that could go several places: doomier territory, blackened-crust aggression, the kind of post-hardcore weight that French extreme bands like Plebeian Grandstand have made their own. Then a riff lands that pulls the song’s vocabulary toward black-metal tremolo while keeping the doom tempo, and the three names on the cover (L. on guitars and vocals, F. on drums, the unattributed bass parts) commit to the genre hybrid the band’s self-description already named. Infernua, the second full-length from Azken Auzi, is six tracks where every one of them carries the same compositional move: hold the slow burn, then commit to the descent.
The band’s self-coined “Occult Doom Sludge” tag is the rare genre label that actually maps to what the record sounds like. Black metal is here in the tremolo passages and the harsh-vocal register. Doom metal is here in the tempo and the riff weight. Sludge is here in the mid-range density and the lyrical aggression. Post-hardcore is here in the rhythmic propulsion of the rapid sections. None of these are sketched in passing; each track works the four elements across six to eight minutes of running time, and the result is a record that does what “Occult Doom Sludge” promises with the consistency of an actual subgenre rather than the looseness of a marketing position.
“Deep Hell” opens the record at almost eight minutes and uses its length to develop the album’s structural vocabulary. The dual guitars stack a wall of saturation across the stereo field, the bass settles into low-end support without claiming articulate voice, the drums move between blast sections and doom-tempo crawls. “SK” follows at five and a half minutes, the shortest piece on the record, and concentrates the band’s compositional vocabulary to its tightest expression. “See You Next Tuesday” is a seven-and-a-quarter-minute piece named for the joke a much heavier title might have been making. “Reptilian” brings in a guest vocal from Nico Voidozer and uses the contrast between voices to develop the song’s central dynamic. “From Hell” closes the record at five and eighteen, the cleanest expression of the album’s structural argument.
The Argonauta Records pressing context matters. The Italian label has been a serious home for European doom-sludge for years (Wolfnaut, Year of the Cobra, Forming the Void), and Azken Auzi’s signing fits the catalogue cleanly. The recording quality is competent modern extreme-metal sound: dense mids, fuzz-heavy guitars, harsh vocals integrated into the instrumentation rather than placed on top, mastering loudness pushed but not destroyed. The trade-offs are the genre’s standard ones; the production is not the story, the compositions are.
For a French trio working their second LP through a serious continental doom label, Infernua is exactly the kind of record Riff Vault exists to point at. Underground enough to slip past the listeners who only follow major-label extreme metal, ambitious enough to commit to a genre hybrid the band coined, consistent enough across six tracks to make the project an actual statement rather than a sampler. Worth your time if you live in the territory between French black metal, sludge-doom and post-hardcore, and you can hear an “Occult Doom Sludge” record as the genre it claims rather than as a marketing position.
The mix is dense, mid-focused and pushed at modern extreme-metal loudness. Dual guitars stack a saturated wall across the stereo field with retained string definition in the cleaner passages; bass functions as low-end support that fuses with the kick in the heaviest moments rather than carving its own articulate voice. Drums sit forward with present kick attack and snare snap, cymbals occasionally pushing toward harshness in the densest passages. Harsh vocals integrate into the instrumentation rather than perch on top, with the guest appearance on “Reptilian” providing contrast through register rather than placement. Mastering loudness is contemporary; dynamic shifts come at the structural level (clean intros, doom-tempo crawls, blast-section climaxes) rather than within sustained walls. The six-track running order moves through the band’s vocabulary with the consistency of a project rather than a sampler.
Standout tracks: “Deep Hell” for the eight-minute opener that establishes the album’s compositional vocabulary. “Black Mass” for the six-minute piece where the trio commits hardest to the black-metal-into-doom-tempo move. “Reptilian” for the guest-vocal track that uses contrast through register rather than dynamic placement.
Infernua is the kind of second album where a band coins a genre label and then makes the label real. Six tracks of Occult Doom Sludge that earns the term, on a serious continental doom imprint, from a French trio that clearly knows the lineage they’re working in. Recommended without reservation, especially if you appreciate genre hybrids that commit to the hybrid rather than just naming it.
