Sodom is the self-titled album by German thrash metal band Sodom released on 21 April 2006. The first pressing comes in a slipcase and includes a full-colour poster of the artwork. "The album is self-titled," Angelripper explains, "because every band needs a self-titled album." Thrash metal is an extreme subgenre of heavy metal that is characterized by its fast tempo and aggression. Thrash metal songs typically use fast, percussive and low-register guitar riffs, overlaid with shredding-style lead work. Thrash metal lyrics often deal with social issues using direct and denunciatory language, an approach which partially overlaps with the hardcore genre.
