Uncle Slam was an American crossover thrash band from Los Angeles, California, formed in 1984 under the name The Brood. They were influenced by punk rock bands of the '80s like Suicidal Tendencies (which featured some of the members of Uncle Slam and The Brood), D.R.I., Corrosion of Conformity, Black Flag and the Circle Jerks, as well as heavy metal bands like Black Sabbath, Iron Maiden, Slayer and Motörhead. Many of their songs are about politics, rebel themes, death, pain and violence.
