Bandcamp El Altar del Holocausto have spent over a decade making instrumental heaviness in Santander, and Ecos, their return after a long quiet, works entirely on contrast. Six tracks that move between vast, reverb-soaked clean passages and dense, fuzzed walls of doom, with a cello drifting through “Sterna” and electronic ambient outros closing several of the pieces, it is post-metal built on the swing between silence and weight, no vocals needed to carry the drama.
The quiet is where they are strongest. The clean, delay-laden guitars open real depth, the drums sit naturally in the room, and when the band stretch out into their long-form builds, the centrepiece “Vórtice” runs nearly twelve minutes, there is a genuine cinematic patience to it. The cello on “Sterna” and the ambient tails give Ecos a reach beyond pure riff, the sense of a band painting rather than just pummelling.
The heavy half is where the production lets them down. When the distorted walls arrive they tend to turn scratchy in the upper mids and muddy in the low ones, the fuzz guitars stacking up until individual notes wash out and the bass goes shapeless underneath, and a couple of the climaxes, the back half of “Vórtice”, parts of “Recuerdo”, lose their impact to that murk. The atmosphere survives. The crushing payoff the builds keep promising lands softer than it should.
Still, Ecos is an evocative, ambitious return, and instrumental post-doom this committed to mood is easy to fall into. Best heard whole and loud, in the dark, where the quiet passages do the heavy lifting and the walls are felt more than parsed. A band worth more attention than their decade in the underground has won them.
Ecos is instrumental post-doom built on hard contrast: vast, reverb-soaked clean passages, a cello threading through “Sterna”, and ambient electronic outros set against dense, fuzzed walls of distortion. The clean, atmospheric half is the strength, delay guitars with real depth and naturally miked drums. The limitation is the heavy half, where the over-saturated rhythm guitars turn scratchy in the upper mids and stack up in the low mids until note definition washes out and the bass goes shapeless, with some climaxes (Vórtice, Recuerdo) losing impact to that mud, and “Vórtice” leaning on programmed-sounding drums. Evocative in the quiet, muddy in the crush.
Standout tracks: Vórtice, Sterna
