Toxicity is the second studio album by American heavy metal band System of a Down, released on September 4, 2001 by American Recordings and Columbia Records. Featuring the heaviness and aggression of their 1998 eponymous debut, it features more melody, harmonies, and singing than the band's aforementioned album. Categorized primarily as alternative metal and nu metal, Toxicity features elements of multiple genres including folk, progressive rock, jazz, Armenian music, and Greek music, including prominent use of instruments such as the sitar, banjo, keyboards, and piano. It contains a wide array of political and non-political themes, such as mass incarceration, the CIA, the environment, police brutality, drug addiction, pedophilia, scientific reductionism, and groupies.
