Formed in 1999 by French black metal multi-instrumentalist Neige (who also worked with Peste Noire, Mortifera, and Amesoeurs), Alcest was originally conceived as a solo project. It would eventually take on the form of a full band as Hegnor (also of Peste Noire) and Arguth joined the fray and released a four-track demo entitled Tristesse Hivernale in 1999. This demo was a more straightforward black metal affair, much different from what would happen next. After that released, Alcest returned to a one-member format, with Neige moving away from the metal overtones of the three-piece and embracing a more atmospheric approach to his work. The 2005 EP release, Le Secret, was more in tune with the project's ultimate goal, which was to put to ear, as it were, Neige's fascination with an "otherworld" -- of sorts -- that had held a fascination for him beginning in his childhood.
