According to singer Russell Allen, the band entered a short hiatus during 2017 in which they did not perform, due in part to his commitment to Adrenaline Mob, although it was announced during a January 2018 interview with Metal Nation that the band had plans to get together in the following months and begin writing a follow up to Underworld. On July 14, 2017, Adrenaline Mob was involved in a serious vehicular accident, which resulted in severe injuries for Allen and the death of the band's bassist and their tour manager. In July 2018, according to Michael Romeo, the band hopes to re-group and make another album, but also said that he was giving Russell Allen some time and space after dealing with the aftermath of the accident, and also his touring commitments with Trans-Siberian Orchestra. In June 2019, Romeo was considering to make their tenth album after they're done touring in August 2019.
