Monumentum is an Italian act responsible of making ambient music strongly electronica influence, at the stake with their “Ad Nauseam” album. Meanwhile, the previous releases, the “Musaeum Hermeticum” demo and the “In Absentia Christi” album (especially this last one) meant a turning point for the focus of dark ambient music, with the ethnic touches, those Christian Death inspired vocals, a strong gothic feeling and an utter atmosphere of gloomy landscapes rarely seen in the scene.
They ultimately released "Metastasi", a full-length album with covers, non previously released tracks, and some new versions of well known songs by them. After that the band, whose only permanent member throughout the years is/ was Roberto Mammarella, only self released a reissue of "In Absentia Christi", in November 2007, in a very limited edition. The band status is unknown, but it seems they disbanded.
