Eisregen is a death and black metal band from Germany that was formed in 1995. The band's chugging, brutal form of heavy metal has made it popular with German fans of the genre, but the band's success hasn't come without a great deal of controversy. The group's music has been indexed by the German government on several occasions due to lyrical content, leading to restrictions on how and where the band can perform and sell its music. In fact, the band is forbidden to play its song, "Krebskolonie," anywhere in Germany. Eisregen's lyrics are often violent, misogynistic and anti-establishment, which, coupled with the pummeling nature of the music, makes for a band that is sure to polarize its audiences' opinions.
