Atrium Carceri

Atrium Carceri is a Swedish musical project by Simon Heath, initially released by industrial record label Cold Meat Industry. Fourteen full-length albums have been released so far, as well as fourteen collaboration albums together with other artists of the genre.

Style and themes
Atrium Carceri is typically described as dark ambient, black ambient and ambient industrial music. Similar to projects like Lull and Lustmord, Atrium Carceri uses synthesizers, sound effects, samples from films and anime, piano and other instrumentation to create slow rhythms, bitter melodies and complex textures generally based on themes of desolation, loneliness (solitary confinement) and environmental decay. Atrium Carceri has been praised by music critics and embraced by a cult audience for its depth of atmosphere. According to Heath himself, each of Atrium Carceri's solo releases are centered around specific 'story arcs' within a 'grand story,' and following the releases of Reliquiae and Void in 2012, has made a flowchart detailing the story progression up to that point. The exact nature of the concept behind this 'grand story' has been intentionally left ambiguous by Heath, who's said it's "up to the listener and his/her interpretation" to piece together this story. The most popular video on Cryochamber is Songs for an empty world with over 3 million views. The Channel is mostly notable for its Winter Ambient Videos.
