After the success of “Volume XI,” Rumble Music Promotions returns with “Volume XII,” another solid and uncompromising chapter in their ongoing effort to showcase underground Heavy Music from around the world. Released on October 01, 2025, and available now on Bandcamp, this new compilation features 13 tracks spanning multiple continents, styles, and sonic approaches — from the densest Doom and Sludge to obscure Drone, Stoner, and Experimental Metal explorations.
Curated with the same underground spirit that made Rumble Music a reference point for heavy music enthusiasts, “Volume XII” once again proves the label’s ability to bring together unknown yet remarkably talented acts from across the globe. The artwork has been designed by Doomolith, while the instantly recognizable logo is signed by Christophe Szpajdel, a true legend in the Metal visual arts. These aesthetic details alone set the tone for what the listener is about to experience — a dark, immersive, and uncompromising journey through sound.
From the opening Hanyut’s “Koboiangkasa,” a massive and mystic Doom voyage rooted in Southeast Asian Heavy tradition, to the closing Zebulon’s “Reap the Fruits of Famine,” which perfectly seals the compilation with apocalyptic energy, “Volume XII” flows as an unbroken ritual of distortion and atmosphere.
Standout tracks such as Witchthroat Serpent’s “Nosferatu’s Mastery” and Mortajas’ “Sangre de mi Sangre” bring a Cinematic and hypnotic dimension, while The Elektrik Demons inject a Psych-Doom pulse tinged with vintage fuzz.
Astral Witch’s “Left Hand Path” delivers one of the most traditional and evocative moments, steeped in Occult Doom and Proto-Metal imagery inspired by the early ’70s school of heaviness.
By contrast, Iron Lungs’ “How to Become a Ghost” drags the listener into the swamp — a slow-motion assault of Sludge riffing, corrosive tones, and suffocating atmosphere, perfectly bridging the first and second halves of the compilation.
In the second half, Samsara Trip’s eleven-minute suite “Se Vuelve Imaginario” expands the sonic landscape into spiritual territories, contrasted by the mechanical density of Winter Nightfall’s “Posthuman,” one of the compilation’s longest and most ambitious pieces.
Despite the stylistic diversity, “Volume XII” feels remarkably cohesive. The sequencing amplifies contrasts while preserving narrative flow, guiding the listener through Heavy lows, ritualistic interludes, and vast Post-Metal textures. It’s a testament to the curatorial vision behind Rumble Music Promotions — a label that keeps giving space to underground acts rarely heard elsewhere.
This new edition also reflects the truly international essence of the Heavy scene today: artists hail from Malaysia, Chile, France, Italy, Norway, the United States, and beyond, confirming once again that Doom and its subgenres have become a universal language for emotion, rebellion, and artistic depth.
“Volume XII” is available now on Bandcamp as a name-your-price download in MP3 and FLAC formats — an essential listen for anyone exploring the darker edges of modern heavy music.
