In 1980 Carlo Kallen, with some high school friends, founded his first band Adolf Streit & die NS-Verbrecher, which first became Psychorotz and then Brutal Verschimmelt.

A cover draft showing an anti-war collage was discarded by Egoldt and replaced by a skeleton warrior with a mohawk fighting against some kind of monster.

Carlo Kallen played later with the Ewings, Chili Confetti and die ueblichen[2] as well as with TLR (Band).

[2] On the occasion of this re-release three of the original members decided to go on a Germany tour as Brutal Verschimmelt with nine concerts in June 2013.

In the summer of 2024 – 40 years after the release of their first album – they produced their second studio LP entitled Alles frisch!
