MonoMassive is back, the festival dedicated to the heaviest metal held for the third time as the main event of the spring in Satakunta on March 7, 2026 at the Winston in Pori.
Four bands performed: Cumbeast, Sewer Altar, Unborn Generation and Whisper.
Crawling from the depths of Helsinki, WHISPER plays old-school death metal, spiced with prog and melodic death metal, offering a fresh yet gritty take on a genre that has been rotting for decades. Founded in 2023, the band’s EPs Xenogenesis and Gravemind have garnered praise for their brutal yet multi-dimensional approach. The band’s sound combines the atmosphere of early Finnish death metal, Finnish prog and the most modern cosmic influences. Despite being an emerging band, they performed with impressive confidence and technical skill.
UNBORN GENERATION has been delivering dirty grindcrust since 2002. The music combines the ruthless expression of grind, the energy of crust, and a hint of northern gloom in the form of melodies. The trio delivered the shortest set of the night — a tight, 30‑minute burst of pure energy.
SEWER ALTAR, a viscous entity of blistering grind, grimy breakdowns, and d-beat human tornados. The band delves into death metal themes of defilement and horror, intertwining them with the pervasive malaise of sociopolitical inequality. Jumping in as last‑minute substitutes for Unknown Subject, the trio rose to the occasion with a tight, well‑performed set.
CUMBEAST – brutal and grooving led metal from Turku since 2005. The band is known for its unique style: Heavy and grooving guitar riffs and strange tricks with a fretless bass combine with funky and pounding drums and inhuman, visceral vocals in an inexplicably tickling way. The green glow of Cumbeast’s RGB LEDs has illuminated festival and gig stages all over Europe and the ridiculously brutal energy of the gigs and the hit songs have infected the audience time and time again to mosh, dance and laugh. With their stage presence, audience engagement, technical skill, and sheer passion for performing, Cumbeast truly delivers the complete experience.

MonoMassive Spring Edition, Pori(Finland) 1.3.2025
Meara Music, after the success of the two summer editions of the MonoMassive festival, opted for a spring edition to satisfy fans of extreme metal music. The festival was held at the Annis culture house in Pori, the bands that played were Putrid Defecation, Inferia, Cannibal Accident, Bob Malmström and Rotten Sound.
Putrid Defecation, founded in Espoo in 2019, proclaims the good news of toilet humor with heavy riffs and a relaxed attitude. The band released their first full-length in early 2025.
Founded in 1989, INFERIA from Lahti is one of the original Finnish death/grind bands, still active today. The band’s grindcore is based on Napalm Death, Deicide and Cannibal Corpse-style rough-and-tumble, mixing their own distinctive death metal and hardcore into this broth. Inferia is characterized by erotically nuanced lyrics, in the porndeath/grind spirit.
Cannibal Accident is a Turku-based hybrid of old-school grindcore, death metal, d-beat hardcore and mosh parties, founded in 2007. The discography includes four albums and a slew of other releases. The fifth full-length, Disgust, was released in February 2025. Live, the orchestra delivers with a fiercely tight and merciless energy.
Bob Malmström, The one and only, The true originators and crowned kings of borgarcore.
Originally from Vaasa, Rotten Sound has been hammering out their relentless grind for 31 years, with no intention of calming down or slowing down. Their latest album “Apocalypse” brought a whole new energy to their live shows. Numerous tours, festivals, albums, EPs and club gigs have honed Rotten Sound into a diamond that sets off car alarms in nearby neighborhoods and forces pits to extreme speeds.
The whole festival was a mix of extreme music, fun and pure energy.

MonoMassive Festival 9.9.2023, Pori (Fin)
The first edition of MonoMassive, organized by Meara Music, was held in Pori at the Annis house of cultures on September 9th. Six bands took turns on the two stages: Anzillu, Atlas, Where’s My Bible, Medeia, Black Royal, and Rytmihäiriö. The festival was sold-out thanks also to the possibility of participation of young people under 18 years of age. Hopefully the festival will be repeated next year.
