Kreator is a thrash metal band from Essen, Germany. They originally started under the name Metal Militia, later Tyrant and Tormentor, finally Kreator. Starting their career in 1982, they played Thrash Metal withVenom influences. Their style of music is similar to their compatriots Destruction and Sodom, the other two big teutonic thrash metal bands from Germany. All three of these bands are often credited with helping create death metal. 

Kreator’s work has been consistently in the vein of pure thrash, with the exception of four albums (Renewal, Cause for Conflict, Outcast and Endorama) during the 1990s when they undertook serious experimentation. Incorporating Industrial, Gothic and Avant-Garde elements into their sound, the results were uneven in some fans’ and also critics’ eyes.

Kreator formed as Tyrant in 1982 in Essen, Germany. The original lineup featured vocalist/guitarist Miland “Mille” Petrozza, drummer Jurgen ‘Ventor’ Reil, and bassist Rob Fioretti. They soon changed their name to Tormentor and released two demos. They changed the name of the band again to the final one, Kreator and signed to Noise Records in 1985. The name Kreator is not just a play on the English word “creator”, it’s also a name of a demon in the German mythology. Mille thought it was a cool name so the band settled with this new name instead of “Tormentor”.

They recorded their debut album, Endless Pain, in just 10 days. Legions of black and death metal bands call it one of their major influences. The band hired the late Sodom guitarist Michael Wulf for the albums tour.
