Demonical was spawned in March 2006 - by former Centinex members Johan Jansson (guitars & vocals), Martin Schulman (bass) and Ronnie Bergerståhl (drums) - with a mission to return to the roots of death metal and deliver a sheer dose of darkness and brutality.
The first audio assault - a four track promo attack entitled "Bloodspell Divine" - was recorded at Necromorbus Studios during July the same year.
In November 2006 Demonical added vocalist Ludvig Engellau to the line-up - 'cause Johan wanted to fully concentrate on the six-string axe - and signed a worldwide multi-album deal with German Cyclone Empire.
The bands first full-length album - "Servants Of The Unlight" - was recorded at both Black Lounge and Necromorbus Studios during January and February 2007 and released in April the same year. In December 2007 the band parted ways with vocalist Ludvig Engellau due to musical and personal reasons. The bands second full-length album “Hellsworn” was recorded at Necromorbus Studios between December 2008 and February 2009 and released by Cyclone Empire in May 2009.
In September 2010 Demonical once again entered Necromorbus Studios in order to record “Death Infernal”, their anticipated third full-length album.
During the fall 2011 drummer Ronnie Bergerståhl decided to leave the band due to scheduling conflicts and he was quickly replaced by Fredrik Widigs.
After “Death Infernal” was released the band decided to add a second guitarist for live situations.
A few session members were used at several tours until Daniel Gustavsson joined as a full-time member during the summer 2012.
The first half of 2013 was spent at both Necromorbus and Wing Studios in Stockholm with the recordings of the bands fourth album, "Darkness Unbound".
After the recording a line-up change took place with Johan Haglund replacing Johan Jansson and Ämir Batar replacing Fredrik Widigs. "Darkness Unbound" was released worldwide in November 2013.In December 2014 Demonical both parted ways with drummer Ämir Batar and guitarist Daniel Gustavsson as well as inked a new worldwide deal with Agonia Records.
The first release for their new label-home,a four track MCD entitled “Black Flesh Redemption”, was recorded at Wing Studios in early 2015 and released in April.
The recording featured session members Eki Kumpulainen on guitar and Kennet Englund on drums.In early 2017 the band parted with long time vocalist Sverker Widgren, due to time- and priority related matters, and replaced him with Alexander Högbom.
At the same time guitarist Eki Kumpulainen and drummer Kennet Englund became permanent members of Demonical making the band a solid and stable unity ready for the things to come.
During the fall 2017 Demonical will record their fifth full-length album - together with a award-winning swedish producer - for an early 2018 release through Agonia Records.
And now they come back with the new full lenght album World Domination.
In the year 2022 they release the seventh album "Mass Destroyer" the last record with the frontman Christofer Säterdal, in the 2023 enter in the line up the new member on vocals Charlie Fryksell from Caedem and they release the new Ep "Into Victory".
