This band is a perfect example of what Italians can do with music! Rules? No way! These guys have been striving against the stream for two decades and do it very well! 

We all know them and we all love them!!! ROTTEN SOUND is the absolute synonym for the word grindcore!!! The band has been playing since 1993 and has been associated with Obscene Extreme since 2000, when they played their very first show outside their native Finland at Battlefield. 

Have you just subconsciously brought your thighs together? No wonder! Here comes a horde that rightfully belongs among the gems of the ultra-brutal Colombian scene!!! AMPUTATED GENITALS have been on the scene since 2003, and every mafioso in Bogota knows them! 

Another band that will make its debut at the Obscene Extreme festival. This time it will be Colombian thrash/hardcore maniacs POISON THE PREACHER!!! Formed in 2021, they have been playing severe music with a huge dose of fury from the very beginning, as a Latin American band can do. 

VOR DIE HUNDE, a band from Passau, Germany, will definitely be a big surprise at Obscene Extreme 2026!!! The quartet, which admire intense grindcore supported by great groove passages, is damn good at what they do!!! 

From the darkest corners of horror comes this rotten super project called SEASON OF THE DEAD!!! And here only the most qualified have come together, but judge for yourselves. 

The next band we're introducing brings a breath of fresh air to thrash metal!!! PHRENETIX is a quartet from the Lithuanian capital of Vilnius, led by the incredibly talented frontwoman Lina!!! 

This band defines the thrash metal genre like only few others!!! The German hydra ASSASSIN has been around since 1985 and is definitely one of the most famous names in this style, which has been kicking our asses so beautifully for more than four decades!!!

MOŽNOST VOLBY? is the name of a project that commemorates the uncrowned kings of Czech extreme music, Gride, and their seminal album released in 1999 as a split album with another now buried extreme band, Mrtvá Budoucnost!!! 

These masters of brutal death grind from France are coming back to Trutnov to unleash absolute chaos once again.

This is a comeback with a big bang. Swedish punk crust band UNCURBED announces its return to the stage to play at selected events in 2026. And one of those places is, of course, the Obscene Extreme festival, which we think is absolutely great. 

One of the next band that will make their debut at the Obscene Extreme festival are these four killers from Budapest, Hungary, RETORSION!!!

Get ready for a total annihilation by this this legendary Massachusetts hardcore punk quartet. Few bands have reshaped the face of hardcore and extreme music like CONVERGE. 

Only underground maniacs will know about this madness!!! FOSSE SEPTIQUE is basically a new name on the ultra-guttural gore grind scene, which was formed in 2024 after the breakup of the better-known Danish band Septage. FOSSE SEPTIQUE is, however, a complete slaughter, where the bar of extremity is raised to an absurd level.

Forged from the ashes of then defunct Centinex in 2006, Sweden’s DEMONICAL have spent nearly two decades perfecting the art of pure, unrelenting Stockholm-style death metal. 

This thrash band definitely does not sit in the shadow of the big German Teutonic four. BONDED is a name that we have been seeing on the scene since 2018, and connoisseurs surely know that the band was formed around former long-time members of Sodom, Bernemann and Makka.

With 4 albums released and a new one on its way for next year, DEVANGELIC are right now considered one of the most solid and relentless brutal death metal bands in action in Europe. Embraced by fans and critics, perhaps as one the most brutal things around DEVANGELIC have built a strong fan base internationally.

Germany, beer, and blastbeat. Anyone who regularly attends OEF won't find this combination particularly extreme, but the band we're introducing to you now, called TFB, really lives up to its name!!! 

For those who like to swim in the dance waters of swaying gore grind, we have great news!!! A flood of the most rancid rectal smegma is rushing towards Trutnov's Batlefield.
