REVIEW: BOCC - Demolarium

Barcelona-based death/doom trio BOCC returns with Demolarium, releasing on September 11th via Night Terrors Records. The record wastes no time establishing its intentions: Heavy, murky and deeply rooted in the uglier corners of extreme metal, it drags death metal, doom, sludge and crust through the mud and comes out sounding appropriately filthy. Rather than relying solely on speed, BOCC understands the power of weight with riffs lumbering forward, guitars remaining saturated and oppressive, while the drums frequently provide the momentum that keeps the record from becoming static.

The title track, Demolarium, is a suitably crushing introduction. It is deep and heavy from the very beginning, pairing guttural vocals with murky guitars and a doom-laden pace that feels almost physically difficult to move through. The contrast comes from the drums, which seem to pull everything forward and give the song a sense of acceleration despite its otherwise sluggish character. A heavy guitar solo arrives almost unexpectedly, breaking through the density and pushing the track into a faster second half before dissonant guitars bring it to a suitably uncomfortable close.

Estigma takes a more atmospheric approach. Its intro is built around a gritty, dissonant and echoing guitar which remains the red string through the song. The drums and vocals gradually add weight, but taking a surprisingly supportive role rather than dominating. The vocals truly only really arrive around the two minute mark, allowing the instruments to establish the mood first. As with the opening track, BOCC eventually shifts gears, with the final stretch becoming noticeably faster. Bass takes centre stage on Escorxador, where its prominent solo and constant low-end presence give the track an impressive sense of depth. The drums also become one of the song's defining elements, maintaining their force right through the ending. It is a good example of how BOCC can make relatively straightforward ingredients feel imposing simply through the way they are layered and performed.

With 4227, the band becomes considerably more progressive and experimental. The drums have a distinctly studio-like feel, while the guitar feels like it’s being tuned or assembled in real time. An inserted piece of audio resembling a news broadcast adds another layer of unease, reinforcing the feeling that Demolarium is interested in more than simply delivering riffs. Calvari (Dels Condemnats) is perhaps the album's most immediate assault. Loud, saturated and brutally direct, it lands like a sucker punch. There is little need for embellishment, the band simply turns up the pressure and lets the sheer density of the sound do the work. Closing track Ànima D’Acer brings back the strong bass and drums that have characterised much of the record. It is a good song, but it feels a bit too familiar by this stage. It is a good song that however feels more like something that might have appeared in the middle of the album than at the end.

BOCC has created a record that feels deliberately unpolished and physical, where the grime, distortion and heaviness are part of its identity rather than imperfections to be cleaned up. The band's Catalan lyrics and connection to Catalan history and folklore further strengthen a sense of unique identity, while the combination of death metal brutality, doom's oppressive weight and crust's confrontational energy gives the album a character of its own. Demolarium is not an album concerned with comfort or easy listening. It is dense, filthy and frequently claustrophobic, but also brings enough movement within that heaviness, to keep it engaging. BOCC's strength lies in knowing when to crawl and when to charge, and in making both approaches feel equally threatening.

Score: 7/10

Demolarium will be released on 11th September 2026 via Night Terrors Records.
