The album's first single, "Nevermore", premiered on May 22, 2015, followed by "Without You" on June 19. They were both officially released on July 22, 2015. The band's guitarist, founder and main songwriter, Michael Romeo, said he was against releasing separated tracks of the album, since it was written to be "a whole".
