In 2016, due to legal issues regarding religious groups in South Africa boycotting the band, they will be performing under the name Χ Ξ Σ there.
Before they formed Rotting Christ, Sakis Tolis, Themis Tolis and Mutilator played in a band together called Black Church, which they started in 1985. They went on to create Rotting Christ in 1987.
Originally started as a grindcore band, but after Satanas Tedeum they became a straight up black metal act.
Sakis (vocalist/guitarist) and Themis (drummer) are brothers.
