The entity Insane Vesper was summoned back in 2002 by Arggon in the aim to glorify the Black Death abomination through extreme music.
First the band used to play raw and primitive black metal rehearsing with various and mostly unconsequent session members. In 2003 the first demo "Unholy Procession" was recorded, containing 5 tracks of pure hate having yet a dirty production but with an undeniable deadly grim feeling.
In 2004 some new songs were recorded for the second demo "Millenium of Decay" but were never released, then an alliance was concluded with the Singapore maniacs from Istidraj and Ironfist to make the split release "Blasphemous Demonic Trinity" containing rerecorded versions of those unused tracks.
The Band knew significant changements in 2005 with the coming of two cursed souls, Asmodeus and Molok, taking the vocals and drums duties. Their collaboration permitted to reach another step towards filth and aggressiveness turning the sound way more darker and stronger than everything done previously.
In 2007 the new demo "Twilight of Extinction" has been recorded containing four brand new tracks of bestial and rampant black metal, combining both the morbid intensity of old Dissection with the twisted fury of old Mayhem, thus being to date the band's most accomplished effort.
Since then, they concentrate on creating the first full length to be spawned out during the forthcoming year...
