The Marble Index is Nico's 1969 album. It is sometimes called the manifestation of a nightmare in music by fans and foes alike. The acoustic and very minimalist album is considered Nico's most influential and avant-garde work, and is cited as a forerunner of the later Goth music movement. Bands such as Dead Can Dance and artists such as Jocelyn Pook were heavily influenced by Nico's music.
