Formation, ''Prince of Maerings'' demo, and ''Fi'mbulvintr''
King of Asgard was formed in 2008 by Karl Beckman and Karsten Larsson, former members of Viking metal act, Mithotyn. Following the release of their 2009 demo, Prince of Maerings, King of Asgard signed with Metal Blade Records. The band's debut album, Fi'mbulvintr, was released in 2010.
''... to North''
The band's second record, ... to North, was released by Metal BladeRecords in 2012. In early 2012, bassist Jonas Albrektsson was quoted on Blabbermouth as saying, "... to North takes off pretty much where Fi'mbulvintr left off, so to say, with a natural development, more varied songs and structures. It's a development of our sound which will be recognized by old fans." Albrektsson went on to say, "this time around I've been more involved in the writing process along with Karl, which kind of shines through, giving the songs a wider perspective." A video was released for the album's lead single, "The Nine Worlds Burn." Digipak versions of the album feature a bonus cover of Isengard's "Winterskugge."
''Karg''
Karg followed in 2014. It would be King of Asgard's final release through longtime label, Metal Blade Records. Karg's release was preceded on May 19, 2014 by the debut of its first single, "The Runes of Hel," which featured an accompanying video. Metal Injection noted a shift in the band's musical direction from the style of King of Asgard's previous outings, stating that Karg, "continues to elaborate on their traditional Viking metal, but looming within it is an ominous forecast of the black metal variety." The album features a cover of Bathory's "Total Destruction."
Signing with Trollmusic, ''taudr''
In 2016, King of Asgard announced they had left Metal Blade Records to join Swedish label Trollmusic. According to the label, the band's fourth release, taudr, was recorded in June, and is expected to see release in October 2016.
