Yacøpsæ is a Grindcore/Hardcore/Powerviolence band from Hamburg, Germany that was founded in 1990.
Yacøpsæ was founded in 1990 in the cultural environment of the local punk and squatting scene. The band name refers to the family name ("Jakobs") of the former singer of local band The DDL's. For the first five years the band existed as duo as a bassist could not be found. In February 1992 drummer Pattex left the band due to "musical differences" and was substituted by Oliver Ebeling a short time later. Up to then Ebeling had played the drums for Hamburg based hardcore band Derider. In January 1996 finally a bassist was found in form of Frank Venet, ex-Sargnagel. The band's line-up is steady since then. They have played the Obscene Extreme festival in 2001, 2005, 2007 and 2012.
Ollie Fröhlich of German "Ox" fanzine named the Tanz, Grosny, tanz... album the "fastest, most honest, most angry and best grindcore album of the year.bloodchamber.de called the album a fast and aggressive mixture of hardcore and grindcore which is seemingly dominated by chaos and utter confusion. But everything had its proper place, and the order in the background works out only little by little. Michael Siewert (of Ox fanzine) categorized the band's music as hardcore in his review of the Yacøpsæ/Sanitys Dawn split 12". He pointed out that the lyrics are in German language, which was unusual for a hardcore band. Despite accordant classification in the media the band it self does not see itself as a grindcore band, but files itself between the hardcore subgenres powerviolence and fastcore. Characteristic attributes of Yacøpsæ songs are blastbeats, stop'n'go breaks, distressing singing and German lyrics critical of society.
