Cannibal Corpse may not experience the smoothest run when they head off to Russia this October. Various Orthodox activist groups have begun to protest the death metal band's upcoming concert dates due to Cannibal Corpse's violent themes.

The band previously faced a ban of cover art and the performance of certain songs in Germany in the past. However, Cannibal Corpse are far from the first band to receive trouble in Russia. Two Pussy Riot members served the greater part of a two-year prison term after protesting against President Putin. Earlier this year, Behemoth were detained by Russian authorities overnight in putrid conditions before being ordered to leave the country. In addition, Marilyn Manson had a couple of shows called off due to protests and bomb threats.

President Putin is a well-known supporter of the Russian Orthodox Church, though he has yet to comment on Cannibal Corpse. 'God's Will' leader Dmitry Tsorionov (Enteo) has spoken out against Cannibal Corpse in a quote from "We send mass requests to the prosecutor, the description of what is happening at the concerts of the group, the texts of their songs, which are described in detail in the rape and murder of children," says Entro.

The Orthodox Union also seeks to ban Cannibal Corpse from playing in Russia. "We seek to ban concerts Cannibal Corpse in Russia. Their work is fully covered by the composition of the crime under the articles of the Criminal Code, for fueling religious hatred, promoting exclusivity, superiority or inferiority of citizens on the basis of their religion," declares Orthodox Union Chairman Roman Pluta in a quote from Yugopolis.
