German underground promoter Rumble Music Promotions is back with “(((Volume 15))),” released on February 18, 2026, via Bandcamp. The fifteenth installment of the ongoing series continues where its predecessors left off: no compromises, no mainstream concessions — just raw, heavy music sourced from the margins of the global underground.
The roster spans an impressive geographic breadth, from Bosnia and Herzegovina to South Africa, from Chile and Mexico to Serbia, France, Denmark, Sweden, and Canada — thirteen acts, each carving their own corner of the Doom, Sludge, Stoner, and Psychedelic spectrum.

— Continuity and Aesthetic —
“(((Volume 15)))” maintains the curatorial consistency that has defined the series since its inception. The cover artwork is once again handled by Doomolith, with logo design credited to Christophe Szpajdel — a name well known in extreme metal circles — and edited by Johnny Rumble himself. The visual identity remains cohesive and unmistakably underground.
The tracklist balances brevity and endurance with purpose: Slôdder and The Curse of Sahara clock in under three minutes, while P+A+G+E+S stretch “The Passage” across fifteen minutes of Cape Town-born doom meditation. Devilsharvest — Hagen locals and arguably the closest act to Rumble’s home base — submit a ten-minute monument with “AsMadAsHell,” mirroring Desert Mantra‘s equally expansive “Bloom” from Torreón, Mexico. The compilation closes with Grusom from Svendborg, Denmark, whose “Memories” offers a fittingly weighted outro.
(((Volume 15))) is available now as a free/name-your-price download on Bandcamp.
