During the summer of 1999 the four members: Tommy Dahlström, Zeb Nilsson, Johan Hjelm and Arttu Malkki of the newly broken up band Defaced Creation decided to form a new death-metal band that would try to create a more pioneering and interesting style, instead of doing the usual “old-school” death-metal, (even though the roots was in the “old-school” death-metal). Morgan Nordbakk joins as fill in guitarist and during the Fall of that year, Aeon recorded their first demo, which included the songs “Return of Apolluon”, “Eternal Hate”, “With Blood they Pay”, “The Awakening”, “Bloodlust” and “Hell Unleashed”. In May of 2001, the 6-track demo was released as a MCD – entitled Dark Order – thru Necropolis Records. Dark Order sold out very quickly and is still in high demand.
Later in 2001, Morgan Nordbakk leaves Aeon, to be replaced by Daniel Dlimi (ex-Equinox ov the Gods). Daniel is an experienced song-writer in Aeon’s style of death metal, so the transition was smooth and easy. In the summer of 2002, drummer Arttu Malkki leaves the band to be replaced by Nils Fjellström followed by work on their first album.
In the fall of 2003, Aeon began recording Bleeding the False, which was released on September 20th, 2005 through Unique Leader. The album was received well in the metal underground with both fans and press.
In April 2006, Aeon hit the road in Europe with Cannibal Corpse and were met with an overwhelming response by the fans. Later that summer, Aeon parted ways with longtime bass player Johan Hjelm (replaced by Max Carlberg), and in July, they signed a deal with Metal Blade Records.
In April 2007 the band recorded the album Rise to Dominate and in September it was released by Metal Blade Records. Much like the previous album, this one received very good response from both media and fans and demand for the band to tour in the North America continued to grow.
In January 2009, the band hits the European roads with Hate Eternal, Misery Index and See You Next Tuesday and after that they continued working on the new album. In September,Aeon parted ways with bass player Max Carlberg, who was replaced by former Satyricon bass player Victor Brandt, and the band recorded the album Path of Fire. In November, Aeonsupported Mayhem on their Swedish dates on their “25 Years of Chaos” tour. In January 2010, bass player Victor leaves Aeon and was replaced by Marcus Edvardsson.
In May 2010, Aeon released their third full-lenght album, Path Of Fire thru Metal Blade Records, which was mixed by multi-talent Erik Rutan at Mana Studio in Florida and mastered by Alan Douches for West West Side Music. Once more the band was met with high praise from the death metal community and press alike with Metal Review saying the album “excels in every department required for a stellar death metal record” and About.com calling the album “a juicy slab of prime-cut blasphemous death metal.” In September of the same year, drummer Nils Fjellström left Aeon and by November the band re-recruits original / founding member, Arttu Mallki, to once again be the force behind the drums. In April 2011Aeon headlined a shorter UK / EU tour with Cerebral Bore and Flyed Disciple
Enter 2012: By the 1st of June Aeon began recording their 4th full-length album and third release for Metal Blade, Aeons Black, with engineer/producer Ronnie Björnström (Garageland Studios). During this recording a 20 minutes documentary was also made, which will be premiered to the masses before the album drops on November 20, 2012.
In 2013 Did a lot of touring promoting “Aeons Black” in UK, Ireland, Germany, Switzerland, Austria, Japan and finally they did a 5 weeks North America tour on Summer Slaughter.
Short after the North America tour Daniel Dlimi decided to leave Aeon after 12 years in the band.
Aeon are currently looking for a new guitar player to fill Daniels spot.
In October 2013 Aeon signs a deal with The Flaming Arts Agency.
