Ghost is a one-of-a-kind band known for their incredible theatrics and costumes. They have prominent religious undertones and satanic lyrics. All of the band members, or the "Nameless Ghouls", are completely anonymous and hidden by demon masks. The lead singer, Papa Emeritus, wears a full-face prosthetic painted as a skull to keep his identity hidden. Papa dresses up as a "demonic anti-pope" for performances, where their theatre skills and arena rock sound really shine.
