Ghost B.C.

Ghost is a Swedish heavy metal band that was formed in Link√∂ping in 2008.
The band is easily recognisable because of its eccentric on-stage presence. Five of the group's six members wear virtually identical, face-concealing costumes.
The most distinguishable member is the vocalist Papa Emritus, who wears a prosthetic face with skull face paint, appearing as what can be described as a "demonic anti-Pope".
The band members' true identities are kept anonymous with the musicians being referred to only as Nameless Ghouls.
