King Diamond is the band that King Diamond (Kim Petersen) formed after the split up of Mercyful Fate - following the departure of Hank Sherman. He was joined by most members of the then defunct Mercyful Fate. The style has lost most of its proto-black metal style and became a progressive metal band. The Satanic focus was replaced by a focus on horror stories. Apart from two albums, each of the albums contained a story told throughout the songs; some stories span more than one album. Only Fatal Portrait and The Spider's Lullaby deviate here, in that only half of the songs form a story while the other songs are independent. His extremely high falsetto vocal style is notable.
