The Dark Third is the first full-length album by Pure Reason Revolution. It was produced by Paul Northfield (Rush, Porcupine Tree, Gentle Giant, Hole) and recorded at Fairhazel Studios and later RAK studios. An earlier single "Apprentice of the Universe" peaked at #74. The title refers to the "Dark Third", the third of a person's life spent asleep and dreaming, with the song on disc 2 "In Aurelia" being based lyrically and thematically around the book Aurelia by Gérard de Nerval.
