Ghost (known as Ghost B.C. in the United States) is a Swedish heavy metal band that was formed in Linköping in 2008. In 2010, they released a 3-track demo followed by a 7" vinyl titled "Elizabeth", and later their debut full-length album Opus Eponymous. The Grammis-nominated album was widely praised and increased their popularity significantly. Their second album and major label debut Infestissumam was released in 2013, debuted at number one in Sweden, and won the Grammis Award for Best Hard Rock/Metal Album.
Ghost are easily recognizable because of their eccentric on-stage presence. Five of the group's six members wear hooded robes and the vocalist appears wearing skull make-up and dressed as a Roman Catholic pope. The band's members keep their identities secret and their names have not been publicly disclosed; the vocalist calls himself Papa Emeritus and the musicians are referred to only as Nameless Ghouls.
