In his most recent visit to terrorize the unwashed masses known as writers, Steel gave me a choice: volunteer to cover Gruta or be voluntold to cover something (else) of his choosing. So it was that I found myself reviewing Gruta’s sophomore release, Hymnus Ad Atram Mortem. Hailing from Bogotá, Colombia, Gruta plays a style of black metal they’ve labeled “Chaos Black, a twisted gnarled amalgamation of black metal’s most vicious bits.”¹ Between this description, loudly antifascist messaging, and opening the record by sampling the Dark Lord Sauron, my expectations were high. Does Hymnus Ad Atram Mortem deliver, or is Gruta just another passionate young band in search of their identity?

The core of Gruta’s sound straddles the line between black metal’s first and second waves. Although Hymnus Ad Atram Mortem opens bright and playful à la Slaegt, it quickly settles into something more traditional (“Niebla”). Drummer Flama unleashes blast beats and d-beat-laden assaults in equal measure, while guitarists Agnen and Garmr wildly oscillate between punky Bathory riffcraft and Immortally searing tremolos (“Oda a la Ruina,” “M.A.F.M”²). The resulting baseline is like a distant cousin to Darkthrone. Vocalist Dagnir is nearly a dead ringer for Mayhem, frog voice and all. Whether whipping up a crowd (“Ramas de Araña,” “Sword of Defilement”) or shouting incantations like Saruman over the winds of Caradhras (“Transfiguración”), Dagnir commands an impressive range of rasps, howls, shrieks, and croaks. Rather than choosing between black metal’s punky origins and the icy, atmospheric howl it became, Gruta uses both as a springboard for what they ultimately create.

“Chaos Black” had me expecting unhinged war metal, heavy dissonance, or traces of grindcore. Not so, apparently. While their blackened core is indeed closest to Darkthrone, Gruta incorporates DSBM atmospherics (“Stygos Tou Kosmos,” “M.A.F.M.”), heavy metal (“Oda a la Ruina,” “Ramas de Araña”³), Slayer-esque thrashing (“Al-Shuhada,” “Sword of Defilement”), punky piss and vinegar (“Ramas de Araña,” “M.A.F.M.”) and even emotive atmoblack structures (“Vorágine Espectral”). Rather than a caustic brew, the result shares much in common with Kvelertak. By injecting their formula with such wide-ranging styles, Gruta offers a fun and engaging ride. In crafting this refreshing take on black metal, Ataecina’s bass unexpectedly steals the show. Surprisingly forward in the mix, it’s vibrant and warm, very like Iron Maiden’s early releases. Ataecina weaves and dances around central riffs and rhythms, nimbly alternating between counterpointed leads and supporting Agnen and Garmr’s guitars (“Oda a la Ruina,” “Ramas de Araña”). Gruta is certainly black metal, but it is their ambitious maelstrom of influences that separates them from the pack.

Gruta’s biggest difficulty is in keeping their momentum up through the album. Opener “Niebla” struggles to get off the ground because of a false ending one minute in, and with a slow, atmospheric interlude that takes up a quarter of the track, “Niebla” feels more like a botched teaser than an actual song. “Stygos Tou Kosmos” suffers similarly. It downshifts from mid-paced, Mayhem-heavy black metal to haunting and eerie DSBM around 1:30, lingering there without clear purpose until it fades out two and a half minutes later. I hate to knock a song that literally screams “Death to Fascist Metal,” but “M.A.F.M.” has the same issue; the first half is an absolutely vitriolic barn burner, but the back half runs out of gas early and takes a couple minutes to eke across the finish line. I think if these songs were cut up differently, or perhaps ordered differently, this may not be as much of an issue, but as it stands, I find myself wanting to skip about a third of the album.

Opening with a soundbyte of Sauron the Deceiver is a good foot to start on, but Gruta doesn’t really need it. Retro guitars, iconic vocals, a deliciously clever bass, and punky, energetic drums come together to honor the greats and forge a path all Gruta’s own. Far from the harrowing trip I expected, Hymnus Ad Atram Mortem has a classic, old school feel, decked out in fun, nostalgic threads. Gruta’s style does come dangerously close to the kitchen sink, and I’d like to see a smidge more focus and a keener ear toward holistic composition on future releases. But problems aside, Hymnus Ad Atram Mortem is a solid and exploratory sophomore effort from a passionate band, and I’ll be very interested to see what Gruta does next.
