The Hellacopters was formed in 1994 by Nicke Andersson as a side project for his main band Entombed, where Andersson composed music and played drums. The original line-up consisted of Andersson (on guitar & vocals), Dregen (guitar), Kenny Håkansson (bass) & Robert Eriksson (drums). After having released two 7" singles ('Killing Allan' & '1995') their debut album 'Supershitty To The Max' was released in June 1996. Shortly after this 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 1997 Andersson, having becomed bored with playing death metal, left Entombed and started to concentrate full-time on The Hellacopters, which became his main musical outlet for the next 11 years. The second album 'Payin' The Dues' was released in October 1997. After touring for the album guitarist Dregen decided to leave the band in 1998 to concentrate on his own band Backyard Babies. Following Dregen's departure, the band used few different session guitarists on tours, e.g. Chuck Pounder, Mattias Hellberg, Scott Morgan and Wayne Kramer filled in on the second guitar.
The third album 'Grande Rock' was released in May 1999 and having not found a permament replacement for Dregen, Lindström and Hellberg contributed on guitar during the recording. The album was also a departure from the punk rock driven style of the first two albums and showcased a more classic rock oriented band sound. For the following tours the band hired a new guitarist, Robert Dahlqvist, who also became a full time member of the band.
On October 26th 2008, The Hellacopters played their last gig at Debaser Medis in Stockholm.
On October 30th 2015, guitarist Dregen confirmed to Swedish Television that original line-up of The Hellacopters are planning a comeback for summer of 2016. So far this includes only one single gig at the Sweden Rock festival and focuses on celebrating the band's early years and specifically their debut album, which becomes 20 years old.
