The founding members of Deathstars knew each other from childhood after growing up in Strömstad, Sweden. The members have considered Deathstars to be a metamorphosed version of black metal act, Swordmaster founded back in 1993. Originally featuring former Dissection drummer Ole Öhman (aka Bone W Machine), guitarist Emil Nödtveidt (aka Nightmare Industries), vocalist Andreas Bergh (aka Whiplasher Bernadotte) and Erik Halvorsen (aka Beast X Electric) on guitar.
The band's very name brings up the image of Star Wars, however it in fact is supposed to be an amalgamation of "Death Metal" and "Stars". The act calls Kiss as an early inspiration, and have been compared to Rammstein, The Kovenant and Marilyn Manson.
By the time their debut album, Synthetic Generation first surfaced in March 2002 on LED Recordings' (later on Nuclear Blast') their style underwent a radical change from basic black metal. These changes could be seen on the band's two pre-Synthetic EP releases of Razor End and Black Medicine. On October 1, 2003, bass player Jonas Kangur (aka Skinny Disco) joined the group; previously he was only present for live sessions.
Plans to commence recording of the second album, however, were delayed as due to their gear being stolen when returning from the Wave Gotik Treffen' festival in Leipzig, Germany in June 2004. However, by October they were back in form to support to the resurrected Dissection at their Stockholm Lilla Arenan gig before undertaking the recording of their next album in early 2005 at the band's own Black Syndicate Studios; that album, Termination Bliss, would arrive in January of 2006 but not before parting ways with guitarist Erik Halvorsen in August, citing, "lack of enthusiasm". Limited edition variants of the album were released with a "Driven On" remix of the track Blitzkrieg by Mortiis.
During this period there was outside band activity with both Emil Nodtveidt and bassist Jonas Kangur securing production credits on the Dissection album Reinkaos; Deathstars also remixed the track Vyperpunk on Dope Stars Inc.'s Neuromance album. As well, the band supported Cradle of Filth on their 2006 tour through Europe. In September 2006, the band announced that Eric Bäckman (aka Cat Casino) was now a full-time guitarist in the act.
Deathstars then opened shows for Korn on their European tour throughout January and February 2008. Deathstars also headlined shows on the side between the dates they performed with Korn. But Öhman would not be present for that tour due to personal reasons. Bergh attributed this to the fact that the drummer "had to take care of his family back home". Fellow Swede Adrian Erlandsson, who had also played the drums for Cradle of Filth, filled in on the drumming duties during the tour.
For the next upcoming studio album, Nödtveidt wrote the song Via The End when he heard of the suicide of his brother, Jon Nödtveidt. On 29 October 2007 Deathstars entered Metrosonic Recording Studios in New York City to begin the recording of their third studio album. The mixing was set for January 2008 with the album scheduled for release during spring 2008 and titled, Deathglam. However after Metallica released Death Magnetic, they soon changed the new album's name to Night Electric Night and jokingly stated that Deathstars themselves inspired the signature font and the track name Cyanide on the Metallica album. The joke went further when Bergh stated that the new album would be titled Master of Muppets (a play on the famed Metallica album, Master of Puppets).
In May 2008, Nuclear Blast' released an ultimate edition of the band's second album Termination Bliss called Termination Bliss Extended containing a CD and DVD. This contained one bonus track, Termination Bliss (Piano Version), but does not include Blitzkrieg (Driven On Version). The special DVD included all the music videos and special "making of" them. They had also released a single DVD entitled Termination Bliss EXTENSION. Night Electric Night would subsequently be released in May, 2009.
Throughout 2010 Deathstars continued touring Europe to support Night Electric Night, and in late May, 2010 Deathstars played four shows in South America. Later the band would re-release Night Electric Night as a two CD and DVD set, with the second CD containing remixes and two unreleased songs and by 2011 a tour of America and one in Europe with Rammstein would commence. On October 24, 2011 Oscar Leander (aka Vice), become the new drummer.
By July 2013 the band parted ways with guitarist Bäckman, who wanted to focus on other things in life; the band would continue as a four-piece for the time being. On June 13th 2014 the band released their 4th studio album, The Perfect Cult.
