Matt Goldman, who produced albums for Copeland and Norma Jean, and Adam Dutkiewicz, guitarist for Killswitch Engage, enlisted as producers. Chamberlain noted that the vocals for the album would sound less like an imitation of former vocalist Taylor, but more like the vocals of Chamberlain's former band.
