They were one of the first, actually the first band in Spain who released grindcore on vinyl. Extreme music survivors know for sure that it's the grindcore combo EL KASO URKIJO. Established in 1987 as EL KASO at that time to be renamed the very next year to their final name EL KASO URKIJO after the murders of Spanish marquis and marquess named Urkijo.

Intensive, uncompromising death/grind. This kind of music will be delivered for the second time at OEF by Mexican American band called ROTTENNESS. A very active band with its roots in Cancún, Mexico  where an underground maniac named Jajleel founded the band as early as in 1994.

This band has come flying as a glowing comet on the metal or rather hardcore scene. Their debut album titled „Inhumaform“ was one of the best albums of 2013. Former or current members of various crust, metal, hardcore squads from Sweden cannot produce bad music. Quite a trivial sentence, but 100% true.

We believe there is no need to introduce this band much. The headliner of the Wednesday OEF SPEED MANIA FEST 2017 is here. Fronted by the queen of thrash metal, Sabina Classen. Yes, the German thrashers HOLY MOSES!!! 

See you in 186 days 17 hours 56 minutes and 15 seconds!!! OEF crew

The whole generations of hardcorer’s dream about this and I suppose also the fans of other styles who know what that name means. INFEST at Obscene Extreme Festival 2017! The pioneers and founders of the style called „power violence“. A style that has inspired hundreds and maybe thousands of other bands that have been destroying the musical boundaries since two decades.

Once a longtime drummer Jon announced his departure lately being substituted by a young Dutch Jan Lugtenburg the world of brutality has come back to life hoping to see this massacre in full strength. Some other line-up changes have been done behind the strings. Jamie`s brother Mike has taken a rest and his place is being warmed up by a talented guitar player from EMBODIED, Torment Joaquin Chavez.

RAZORRAPE was estabilished as a one-man project by Martin Schönherr, ex-drummer of the bands like Deranged, Splattered Mermaids or Virgin Sin, in 2004. RAZORAPE is quite unusually a gore/grind band hailing from the European cradle of traditional death metal known as Sweden. The guys added the line-up in 2006 putting out several recordings in different formats together with the well-known Rotten Roll Rex label.

Today we introduce to you one of the top grind acts from our neighbours from Slovakia, EMBOLISM. The band around the Kotrik´s brothers was established in 1997 and soon after their start they released a demo that greatly describes their „Grind´n´Roll“ sound. Other recordings as splits or two full-length albums followed.

In this case the speed really prevails. Absolute grind core with a small touch of crust and hardcore, this is SLAVEBREED, a quintet from Athens, Greece. They have been grinding their core for more than 10 years and certainly they are one of the leaders of the European grind core scene.

Latin-American cult band SADISM at OEF 2017!!! The band was established as early as in 1988 and together with their buddies from Pentagram Chile they are the pioneers of extreme metal in Chile. Old school death metal is what these guys swear on and the list of their recordings indicates how very active they still are. 

Despite the fact they have existed for 10 years they are still quite new and unknown. BLACK SKIES BURN from Oxfordshire, England have taken a fancy to a brutal noise in a grind death style with DIY ethics. They have managed to support some big names such as Sepultura or Extreme Noise Terror amongst others and to release several DIY recordings.

If you currently search for bands to sound similar to Tragedy or From Ashes Rise but without being awkward, whining neo-crust copies at the same time, we just have for you a delicacy from Sweden called MYTERI!

Wow! They are back again! Our „again“ does not definitely mean some annoyed moaning but the opposite. We look forward to this band and you do for sure together with us. WOLFBRIGADE. The founding stone of the world hardcore/punk scene.

Here we have another comeback in the grindcore family. The Polish band PSYCHONEUROSIS that had a very active period between 1991 and 2001 when they played many shows and did even more recordings disbanded due to their professional responsibilities.

An absolute BLAST!!! All of us know of course the metal legend, Danny Lilker, and all his bands and projects. He has graced Trutnov Battlefield with his presence a few times but this year it will for certain be very much special. 

This bizarre trio from Italy called SHITFUCKINGSHIT presents really an insane mixture of the most extreme musical styles like grind core, gore death and Italian 80´s hardcore. It started just as a one man noise core project and in the course of time it evolved into a trio of maniacs who fucking bomb it.

None of you would tell this crazy group celebrated their 20th anniversary this year, wouldn't you? But it is the truth. Formed in Teplice in 1996! Another interesting detail is their regular debut album was released this year only. After 20 years! Personnel changes have not so far allowed for the band to complete something complex. 

The Finnish grindcore veterans INFERIA will be back at the OEF's stage after many years. Established as early as in 1989 and still loyal to their grindcore roots such as early Napalm Death mixed with a huge dose of extreme hardcore and death metal. 

Of course there will be place for Brazilian bands in the line-up for 2017. What would Obscene Extreme Festival be without this unique unrestrained underground scene? The chance to show their energetic grind with punk explosions will be given to TERROR REVOLUCIONÁRIO.
