On 12 May 2015 Simpson revealed via
Instagram that the band had returned to the studio to work on new material with long-time producer Carl Bown and consequently began using Twitter to provide updates on the progress of the album's recording process. Bassist Dan Haigh took to Twitter and Instagram on 20 August to begin posting brief video clips of recording sessions for 'Behind the Devil's Back' in the build-up to the album's release.
Simpson claimed that the album consists of material "amalgamated" during the band's five-year hiatus, and that the release was initially planned as an
EP, although recording did not begin until 2015. In interview, Simpson claimed that his favourite track off the record was 'Sharp Tongue', also noting that drummer Omar Abidi's favourite was 'Dive', a track which he stated "really allowed [me] to get lost in the sound." The mindset of the band going into the creation of 'Behind the Devil's Back' was different to the approach they had taken on any other album due to the ethos of what Simpson describes as wanting to "keep moving in a new direction", with the guitarist and vocalist explaining that "our fans are the ones who we're making this album for. We're not going out with this record to try and conquer the world, we're trying to reinvigorate our fan-base and really do this for them." 'Behind the Devil's Back' is also notable as being the first Fightstar album on which all four members of the band share songwriting credits and regarding the writing process of the album, bassist Dan Haigh stated that "some of the traditional writing goals were altered for this record" as "all boundaries were removed" and "the full extent of the individuals within the band's influences were allowed to come to the table", which he intimated was one reason for the heavy sound of the album. This sentiment was echoed by guitarist Alex Westaway who explained that the material may have taken such a direction as a result of the five-year "drought in [their] creativity on the heavier side of things", as during the band's hiatus their respective musical projects greatly differed stylistically from the sound generally associated with Fightstar. Simpson also attributed the album's sound to the band utilizing 7-string guitars for the first time, stating that as a result the album was "much heavier by its very nature". Another significant element of the album's composition was the introduction of synthesizers and electronic instrumentation for the first time on a Fightstar release. Following Haigh and Westaway's work within electronic side project Gunship, the presence of synthesizers was consequently an element available within the studio during writing sessions, with Haigh stating that it "evolved naturally" and "slowly became the thing we were doing this record with" in order to "augment what we were doing". Electronic instrumentation features on all ten of the album's tracks; making use of analogue synthesizers, sequencers, custom patches and filter sweeping techniques. ==Artwork==
