Possession has been produced by Bart Gabriel (SACRED STEEL, SABATON, BURNING STARR, MORTICIAN). The band again invited members of other bands to sing guest parts on new album: in the song 'Fight Evil With Evil' we can hear the legendary US singer Harry Conklin (JAG PANZER, TITAN FORCE, SATAN'S HOST), while in 'Julia Is Possessed' we can hear growling voice of Sataniac, vocalist of the German black/thrash metal act DESASTER. Except that in one of the songs we can hear... more than 50 fans of the band, who were invited to "scream" on the new album via band's official Facebook page.

The limited vinyl LP version of Possession will include hidden surprise track, the regular CD version will include cover version of the RIOT classic Thundersteel.
