The Hellacopters was initially a side project for Andersson, whose main focus was composing/drumming for the seminal death metal group Entombed, but in 1997 he decided to quit in Entombed and The Hellacopters became his main musical outlet. Band's original line-up consisted of Andersson (on guitar & vocals), Dregen (guitar), Kenny Håkansson (bass) & Robert Eriksson (drums). After releasing their first album 'Supershitty To The Max' in June 1996, keyboardist Anders Lindström (aka Boba Fett) also joined the band, first as live/session musician, and few years later (in 1999) as a a full time member.
In 1998, after touring for their second album 'Payin' The Dues', guitarist Dregen left the band and decided to concentrate more on his own band Backyard Babies. Following his departure, the band used few different session guitarists for tours and for recording (e.g. Chuck Pounder, Mattias Hellberg, Scott Morgan and Wayne Kramer), but didn't find a suitable replacement until in 1999, when Robert Dahlqvist joined the group, first as a touring guitarist and then as full-time member. With this "final" line-up the band released four more albums and numerous singles and EP's before deciding to call it quits in 2008. Their last gig was on October 26th 2008 at Debaser Medis in Stockholm.
Band's hiatus lasted for about seven years as the band's original line-up made a comeback in the summer 2016 and played two gigs to celebrate the 20th year of their debut album.
In February 2017 guitarist Robert Dahlqvist died at the age of 40.
The band plans to continue the celebration of their early years also in the summer 2017. This time also playing material from their second album.
