Sickening Horror was created on January 2002 by George Antipatis (guitars, vocals), Ilias Daras (bass) and George Kollias (drums) to explore the boundaries of extreme music. At first the band was influenced mostly by technical Death Metal and released a 3-song demo cd, simply entitled "Promo 2003". At the time, George Bokos was on the 2nd guitar for a while. As time passed the band incorporated many diverse elements in its music, from experimental black metal to jazz and industrial. The soundscapes got more multi-layered, which is evident on the debut album "When Landscapes Bled Backwards".
