Formation and first releases (2005–2006)

Lifelover was formed in June 2005 in Stockholm, Sweden by the two individuals Jonas "B" Bergqvist and Kim "( )" Carlsson. A demo called Promo 2005 was recorded the same month, but was never officially released and consisted of Carlsson and B playing guitars provided with ambient sounds across two very long tracks both totaling up to nearly an hour of recording length, the band described these two tracks as "improvised misery". After this release, the recording of Pulver began in April 2006, along with a major shift in musical direction compared to the Promo 2005 demo. The backing vocalists/lyricists LR and 1853 were recruited to the band at this time, and the album was finished in May 2006. It was released by Goatowarex in July 2006.

Erotik, Konkurs and Sjukdom (2007–2011)

The band's second album Erotik, was released by Total Holocaust Records on 24 February 2007; guitarist H. had joined the band by this time. In late 2007, Lifelover signed a contract with Avantgarde Music and recruited two new members, Fix on bass and S. on drums for upcoming live shows. LR left the band in April 2008. Lifelover played their first live show in Stockholm in September 2008 and their third album, Konkurs, was released by Avantgarde the following month.

Osmose Productions re-issued both Pulver and Erotik on CD in 2009, Erotik was re-issued on 21 January 2009 and Pulver on 7 May. Member 1853 and live drummer S. both left the band in May 2009. Lifelover released a mini-album, Dekadens, in July 2009 (on Osmose Productions), the first (and only) Lifelover release with real drums which is in contrast to the drum programming the band would use on all their other albums. The drumming was provided by the band's then newest member Non. In February 2011 their fourth full-length album, Sjukdom, was released by Prophecy Productions. Drummer Non had left the band by this point, while LR and 1853 returned to contribute to the album.

The death of B and final performances (2011–2015)

On 10 September 2011, it was confirmed that band member B died the previous day.^[3] An official statement released on 16 September stated that he had died in his sleep after overdosing the night before on his prescription drug medication. It was proven to be an accidental death after an investigation following had suicide and foul play ruled out, and an official autopsy report released months later indicated "poisoning and overdose"^[4] as the cause of death. The remaining members ultimately decided to split up, citing B's irreplaceable role as songwriter and lead composer, and stated that their final shows were those performed in Belgium and the Netherlands the weekend following B's death.^[5] After these concerts, the band had planned on playing one more show on 14 October 2011 dedicated to B, but later decided against it, laying the band to rest out of respect to him. Despite this, Lifelover did perform one more live show in November 2015 for the band's 10th anniversary since they formed in 2005. The concert took place in Quebec, Canada, which was the first time ever that Lifelover performed a show outside of Europe.^[6]
