IT had already planned to create the band in 1987, but it was not until 1990 that he found the right members to do it. The same year, they recorded their first two demos. After the release of the first demo, they fired their bass player, Ext. After the release of a 7-inch EPEvil in 1991, All began to drink heavily and was forced to leave the band. IT then found a new member in "Evil". Around this time, IT reunited with All to form the side project, Vondur. Abruptum was signed to Euronymous's label Deathlike Silence Productions, on which they released two albums. Euronymous described them as "the audial essence of pure black evil", and IT considered Euronymous to be "a true ally". After Euronymous's murder, Abruptum contributed the opening track to the compilation albumNordic Metal: A Tribute to Euronymous. Controversy surrounded Abruptum's close relationship with Euronymous, with Varg Vikernes specifically referencing Abruptum when recalling his version of the events and motives leading to the death of Euronymous. Vikernes, claiming that he killed Euronymous in self-defense, recalled in a 2006 interview: It has been wrongly rumored IT left the band and the black metal scene altogether in 1996, following numerous threats made to him and to his family. According to IT himself and his sister/manager, that was not at all the reason for his departure from the scene, as he had simply been wanting to leave for some time until he ultimately did. Evil kept Abruptum going and released material on his own record label, Blooddawn Productions, until 2005 when he announced that he had ended Abruptum. Since Abruptum's disbanding, IT joined an industrial band called 8th Sin, and was briefly involved with the band War along with All. All worked with IT again in Ophthalamia, but that band has also disbanded. IT eventually died on 8 February 2017, aged 44. Evil continues his work with Marduk and Death Wolf, yet brought Abruptum back in 2008, recording and releasing an EP that same year and a full length in 2011 under his Blooddawn Productions label.
Music themes and style
While Abruptum is classified as a black metal/dark ambient band, the band took a different approach to their music. They did not focus on creating any structured songs, and mostly just made noise. Earlier material had shorter songs but their later releases typically included one or two tracks with more than forty minutes of music. They primarily used standard drums, guitars, bass, keyboards and other various instruments, but what stood out even more was the screaming, as the band supposedly tortured and cut each other during their recordings. Whether this is true or not has never really been verified. This led to Euronymous' now famous distinction of Abruptum as "The Audial Essence of Pure Black Evil". After IT left the band, Evil changed the band's musical style to more dark ambient/noise and dropped most of the metal sound.
