On 20 November 2017, guitarist Fredrik Åkesson stated that the band will not have any gigs in the upcoming months, until the 2018 summer festivals. During this break the band will focus on writing songs for the new album. On 11 July 2018, during an interview with FaceCulture, Åkesson said "I've recorded a lot of solos so far.
