Their current line-up consists of Diamond, LaRocque, guitarist Mike Wead, drummer Matt Thompson, and bassist Pontus Egberg.

Three more albums followed – "Them" (1988), Conspiracy (1989) and The Eye (1990) – before the band went on hiatus around 1992, when King Diamond (along with Denner and Hansen) reformed Mercyful Fate.

King Diamond's studio output has been minimal since 2007's Give Me Your Soul...Please, though the band has continued to perform live and has occasionally been teasing more than one upcoming album.

[5] The band was formed in 1985 by vocalist King Diamond, guitarist Michael Denner, and bassist Timi Hansen.

[1][2] The three had recently departed from the group Mercyful Fate, which fell apart due to musical differences between Diamond and guitarist Hank Shermann.

[1][2] To round-out the line-up of the King Diamond band, the group hired drummer Mikkey Dee and guitarist Andy LaRocque.

[3][18] Following the completion of the Abigail tour, guitarist Mike Moon and bassist Timi Hansen were replaced by Pete Blakk and Hal Patino, respectively.

[40] After the album's release, guitarist Glen Drover, drummer John Luke Hebert and bassist Paul David Harbour were replaced by Mike Wead, Matt Thompson and Hal Patino respectively.

[41] It was also the first King Diamond album since 1990's The Eye to feature bassist Hal Patino, who rejoined the band during the recording process.

[45] During the supporting tour for The Puppet Master, the band recorded the live album Deadly Lullabyes, which was released 21 September 2004.

[47] In April 2006, former bandmate Mikkey Dee (currently with Scorpions, formerly with Motörhead) made a guest appearance at King Diamond's sold-out gig in Gothenburg, Sweden.

[55] On 27 January 2012, Diamond made a special appearance at the "5th Annual Nomad Recording Studio Throwdown", performing three songs: "The Family Ghost", "Evil" and "Burn".

[56] Vocalist King Diamond stated that the band was expected to begin writing new material for their thirteenth studio album in the fall of 2012.

In October, King Diamond announced a new compilation titled Dreams of Horror which was released in November through Metal Blade Records, covering the band's entire career.

[60] King Diamond took part in the 2015 Rockstar Energy Mayhem Festival along with bands such as Slayer (who was chosen as the headliner), Hellyeah, The Devil Wears Prada, Thy Art Is Murder, Jungle Rot, Sister Sin, Sworn In, Shattered Sun, Feed Her to the Sharks, Code Orange and Kissing Candice.

[61] At the 8 July 2015 show in Milwaukee, Wisconsin, King Diamond was forced to perform without his signature face paint due to a severe eye infection, in which doctors advised against the use of any makeup.

[73] On 15 October 2024, during a performance at the Port Authority of San Antonio, King Diamond debuted two new songs called "Spider Lilly" and "Electro Therapy".

[74] On this tour, the band was joined by Myrkur on keyboards,[75] and she appears on the studio recording of "Spider Lilly", which was released as a single on 17 December.
