The project sees the debut of new vocalist Papa Emeritus III alongside the Nameless Ghouls following the resignation of his three-month older brother Papa Emeritus II, who himself took over from original singer Papa Emeritus.

"Meliora" - latin for "better" - follows the band's second album and major label debut, 2013's "Infestissumam" (latin for "hostile"), which debuted at number one in Sweden and won the Swedish Grammis Award for Best Hard Rock/Metal Album.
