The final weeks of 2025 brought yet another devastating announcement wave for Obscene Extreme Festival 2026, further expanding the Battlefield with grindcore avant-garde, Scandinavian crust fury, old-school death metal legends and absolute underground cult icons. Between November 25 and December 9, the festival once again demonstrated why OEF remains one of the few places on earth where every corner of extreme music can collide into total sonic destruction.
The madness began on November 25 with Californian experimental grinders BAD ACID TRIP. Since 1989, the band has existed as one of grindcore’s strangest and most unpredictable anomalies, constantly twisting the genre through bizarre avant-garde experimentation, frantic blastbeats and influences pulled from seemingly incompatible musical worlds.
Rather than simply worshipping old-school grindcore traditions, BAD ACID TRIP has spent decades reshaping the style into something completely their own: chaotic, hyperactive and full of sudden turns and schizophrenic atmosphere changes. Their latest album “Decency Anomoly” continues refining this bizarre sonic identity, proving the band remains as creatively dangerous as ever.
For fans searching for something truly different within extreme music, the organisers strongly recommended not missing the Obscene Extreme debut of BAD ACID TRIP, promising a unique experience somewhere between sonic brutality and total absurdity.
The following day introduced Mexican speed-thrash blackened maniacs PHANTOM. Formed only in 2021, the young quartet already embodies everything fans love about the Latin American underground: aggression, passion, raw old-school spirit and impressive musicianship far beyond their years.
Combining thrash metal, black metal and speed metal exactly in the spirit of the 1980s underground, PHANTOM delivers violent riffs and nonstop energy with a hunger that instantly separates them from countless modern retro-inspired acts. According to the organisers, the band already sounds destined for bigger things, and their appearance at Obscene Extreme Festival 2026 could easily become one of the breakout performances of the entire event.
Scandinavian crust warfare arrived on November 27 through Swedish d-beat force SVAVELDIOXID. Over the last decade, the band has become one of the most respected names in modern Scandinavian hardcore punk thanks to its savage fusion of Discharge-style d-beat, Anti Cimex aggression and Japanese hardcore chaos.
The organisers highlighted the significance of 2026 marking exactly ten years since the release of the band’s debut album “Ändlös Mardröm”, while also pointing out how difficult it is for the group to perform live due to members being scattered across Sweden. Featuring musicians connected to bands such as Warvictims, Protestera and Disfear, SVAVELDIOXID arrives at OEF carrying the legacy of classic Scandinavian hardcore into a new generation.
On November 30, German death metal veterans FLESHCRAWL returned to the Battlefield. Originally formed in 1987, the band remains one of the longest-running and most respected pillars of European death metal, responsible for classics such as “Descend into the Absurd”, “Impurity” and the fan-favourite “Bloodred Massacre”.
After enduring the tragic death of vocalist Sven Gross, FLESHCRAWL fought through adversity and rebuilt itself with renewed determination. Fronted now by Borisz Sarafutgyinov, the band continues delivering the same crushing old-school brutality that defined its legacy for decades.
The organisers described their latest album “Into the Catacombs of Flesh” as proof that FLESHCRAWL still reigns through pure rotten heaviness, explosive riffs and uncompromising death metal devotion. At Obscene Extreme Festival 2026, fans can expect a setlist packed with classics and total German death metal destruction.
December opened with the return of Swedish punk rock’n’roll outlaws FREDAG DEN 13:E. Formed in 2006, the band combines d-beat punk aggression with rock’n’roll swagger, darkness and melancholic atmosphere into one especially explosive Scandinavian cocktail.
Celebrating twenty years as a band during Obscene Extreme Festival 2026, FREDAG DEN 13:E are preparing a special anniversary set spanning their entire discography. More than a decade after their last appearance at the Battlefield, the organisers promise another furious collision of punk chaos, darkness and nonstop movement in the pit.
Young Canadian grinders BODYROT entered the line-up on December 5. Although still relatively unknown in Europe, the Victoria-based quartet quickly impressed the organisers with its filthy old-school grindcore approach, crushing speed and violent energy.
Formed in 2021, BODYROT currently has only one EP — “Fleshwork” — but a full-length album is already on the way ahead of their upcoming European invasion. For fans craving raw and straightforward old-school grindcore, the organisers made it clear: this is a band worth paying serious attention to before the rest of the underground catches up.
On December 7, Ohio blackened death metal hellraisers NUNSLAUGHTER officially returned to Obscene Extreme Festival after a twelve-year absence. Since 1987, the legendary underground institution has built one of the most absurdly massive discographies in extreme metal history, approaching nearly two hundred releases.
Blending death metal, thrash, punk and hardcore energy into one infernal attack, NUNSLAUGHTER continues to tour constantly around the globe while maintaining the same savage energy that turned them into underground legends decades ago. The organisers described the band’s live intensity as a “hellish metal hammer strike” capable of smashing directly through the Battlefield itself.
Finally, on December 9, OEF welcomed back one of its most beloved cult acts with the return of American murder-metal legends MACABRE. Returning to the Battlefield for the fifth time, the infamous trio once again brings its completely unique “Macabre metal” back to Trutnov.
Since the late 1980s and their debut “Shit List”, MACABRE has developed an entirely singular style built around serial killer themes, frantic songwriting, bizarre humour and unexpectedly catchy melodies. Albums such as “Carnival of Killers” helped turn the band into absolute underground icons impossible to imitate successfully.
The organisers made clear that nobody has ever truly managed to replicate what MACABRE does: blending madness, melody and horror into something simultaneously grotesque and strangely addictive. At Obscene Extreme Festival 2026, the return of Zodiac, Dahmer, Ed Gein and the rest of the band’s infamous cast of killers promises another unforgettable descent into musical insanity at the Battlefield.
