AK AUSserkontrolle (often stylized AK Ausserkontrolle) is a German rap act originating from Berlin, associated with the gangsta rap and trap scenes. Emerging in the 2010s, the project is led by a Turkish-German rapper known as AK, who became known for gritty street narratives, a raw vocal delivery, and production that draws on contemporary trap beats and minimalist, bass-heavy arrangements. The music frequently employs dark, aggressive themes and a confrontational persona, reflecting urban life and outlaw imagery common to German drill-influenced and gangsta rap circles. AK Ausserkontrolle has been part of Berlin’s modern hip-hop landscape and has collaborated with other artists in the German rap community.
