Ghost, also formerly known as Ghost B.C. in the United States, is a Swedish rock band that was formed in Linköping in 2006. In 2010, they released a three-track demo followed by a 7" vinyl titled "Elizabeth", and later their debut full-length album Opus Eponymous. The song Ritual was chosen by Kerrang! Ghost is easily recognizable owing greatly to its eccentric on-stage presence. Seven of the group's eight members, its 'Nameless Ghouls' wear virtually identical, face-concealing costumes.
