Sodom is a 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 (who was a member of Sodom from 1987 to 1989 and rejoined in 2018) 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 (except Tankard) 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.
