Alcest is a French post-black metal band from Bagnols-sur-Cèze, founded and led by Neige. It began in 2000 as a black metal solo project by Neige, then became a trio, but members Aegnor and Argoth left the band following the 2001 release of their first demo, leaving Neige as the sole member. Neige began incorporating elements of shoegaze and post-metal into the project's sound from 2005 onwards. In 2009, drummer Winterhalter from Les Discrets joined Alcest, after eight years with Neige as its sole full-time member.
