Their current line-up consists of lead vocalist and rhythm guitarist Miland "Mille" Petrozza, drummer Jürgen "Ventor" Reil, lead guitarist Sami Yli-Sirniö, and bassist Frédéric Leclercq. The band's line-up has changed multiple times throughout its 44-year career, most noticeably their bassists and lead guitarists. Petrozza and Reil are the only two original members left in Kreator, although the latter left the band in 1994 but rejoined in 1996. Yli-Sirniö has been the lead guitarist of Kreator since 2001, while Leclercq joined in 2019 as the replacement of Christian "Speesy" Giesler, who had been in the band since 1994.

Sodom is a German thrash metal band from Gelsenkirchen, formed in 1982. They have gone through various line-up changes, with bassist/vocalist Tom Angelripper the only constant member. The band is currently composed of Angelripper, guitarists Frank "Blackfire" Gosdzik and Yorck Segatz, and drummer Toni Merkel. Sodom has been referred to as one of the "Big Four" of Teutonic thrash metal, along with Kreator, Destruction and Tankard. Sodom heavily influenced the German black metal scene, and is regarded as a pioneer of death metal. Referred to as the most Venom-blackened of German "Three Kings", Sodom further merged thrash and death metal into a "wicked and decadent sound."

Sacred Reich is an American thrash metal band from Phoenix, Arizona, formed in 1985. As of 2025, the band's lineup has consisted of vocalist-bassist Phil Rind, lead guitarist Wiley Arnett, rhythm guitarist Joey Radziwill, and drummer Eduardo Baldo. Former members include rhythm guitarist Jason Rainey, and drummers Greg Hall and Dave McClain. Their music often features mid-tempo song structures as well as musical and lyrical influences from punk rock and hardcore punk, with their lyrics focusing on political and social topics. The band is credited with leading the second wave of thrash metal in the late 1980s.

Tankard is a German thrash metal band from Frankfurt, founded in 1982. Alongside Kreator, Destruction and Sodom, Tankard is often considered one of the "Big Four" of Teutonic thrash metal. Stylistically, Tankard has consistently played thrash metal that thematically centres primarily on alcohol reverence, unlike the remaining "Big Teutonic Four", who are all known for covering such topics related to death, politics, violence and anti-fascism.
