10 Strangest Concept Albums

10. Abigail - King Diamond

Formed in 1985, Danish heavy metal band King Diamond have devoted a significant amount of their discography to concept albums, perhaps none more curious or convoluted than 1987's Abigail, the band's second studio effort.

This record is one of the group's most popular sets, with several re-releases and a 25th anniversary edition available. The album, in fact, has outlived many members of the band, with King Diamond himself (vocals) and Andy LaRocque (guitar) the only constant members.

The record's plot is as dark as they come. You could well imagine film-maker Ari Aster committing this twisted tale to celluloid. Set in 1845, the narrative follows a young couple, Miriam and Jonathan, as they move into a newly-inherited mansion, despite dread warnings from mysterious horsemen.

The ensuing hauntings, omens and trips back in time could fill this entire list by itself. Expect ghost babies, broken necks and an ending which is too distasteful for words.
