Deadlock is a German metal band known for their fusion of melodic death metal with elements of metalcore and symphonic metal, creating a unique and intense sound. Formed in 1997, their music often features a dual vocal approach, combining guttural growls with soaring clean singing, often provided by female vocalists alongside male counterparts, which has become a distinctive aspect of their style. The band’s lyrics frequently delve into topics such as environmentalism, personal struggles, and social commentary, wrapped within their aggressively beautiful compositions.

Over the years, Deadlock has evolved their sound while maintaining a commitment to intensity and melody. Their album "Wolves" (2007) marked a turning point, introducing more clean vocals and symphonic elements. This progression continued with subsequent releases such as "Manifesto" (2008) and "Bizarro World" (2011), further refining their melodic sensibilities. "The Arsonist" (2013) showed a return to a heavier sound, while still keeping the melodic and symphonic trademarks. The band celebrated their longevity and revisited their past with "The Re-Arrival" (2014), featuring re-recorded versions of older songs and new material. Their latest studio album, "Hybris" (2016), received acclaim for its mature songwriting and production, continuing to cement Deadlock's place in the world of heavy metal.
