German thrash metal band from Gelsenkirchen, formed in 1981. They have gone through many line-up changes, leaving bassist/vocalist Tom Angelripper as the only constant member. The band is currently composed of Angelripper, guitarists Frank "Blackfire" Gosdzik and Yorck Segatz, and drummer Toni Merkel. Along with Kreator, Destruction and Tankard, Sodom has been referred to as one of the "Big Four" of Teutonic thrash metal. While three of those bands created a sound that would influence the death metal and black metal genres, Sodom's early music style would greatly influence many late 1980s and early 1990s black metal bands more than others.
