The band was formed on January 2002 by George Antipatis (guitars, vocals), Ilias Daras (bass) and George Kollias (drums, Nightfall). After a very short time the band started completing its first songs which were floating around technical Death Metal forms in the likes of Cannibal Corpse, Morbid Angel, Death and Atheist.
After a year-and-a-half of non-stop rehearsing and killer live shows, the band recorded the demo "Promo 2003" in the Fall of 2003 which received great reviews worldwide for its innovative and precise sound. At the time, the band had George Bokos (Rotting Christ/ex-Nightfall) on the second guitar, who left after a while due to increased obligations. In the summer of 2004 George Kollias joined the US death metal band Nile and recorded "Annihilation of the Wicked" album. By 2005 Sickening Horror had completed the song-writing of their first album.
Meanwhile the band's influences had expanded in a wide spectrum which included experimental black metal bands like Ved Buens Ende, Dodheimsgard, Virus and jazz-fusion artists like Charlie Parker, Dave Weckl, Virgil Donati. All these elements filtered by their unique "Sickening Horror" point of view, in a Death Metal basis, plus many industrial samples and loops created what is now called "When Landscapes Bled Backwards". The band's debut album was recorded in Athens and mixed by mastermind Neil Kernon. As for the lyrics, they have to do with quite simple - often personal - subjects, regarded from a completely strange and surrealistic aspect. Eventually the band reached to an agreement with Neurotic Records to unleash "When Landscapes Bled Backwards" in Spring 2007 and everyone involved in this recording has very high expectations, as the album's sound is really fresh and has a vast variety of the deepest, strongest and darkest emotions..
