Tankard is a German thrash metal band from Frankfurt, founded in 1982. Alongside Kreator, Destruction and Sodom, Tankard is often considered one of the "Big Four" of Teutonic thrash metal. Stylistically, Tankard have consistently played thrash metal that thematically centres primarily on alcohol reverence, unlike the remaining "Big Teutonic Four" (Kreator, Destruction and Sodom), who are all known for covering such topics related to death, politics, violence and anti-fascism.
