Nachtmystium is an American black metal band formed by Blake Judd, formerly known as Azentrius, and Pat McCormick. The band's name is derived from the German word Nacht meaning "night", and the made-up term mystium which resembles the Latin adjective mysticum. Judd and McCormick combined the words to create the band's name, which they state means "Encompassing Darkness". Nachtmystium released multiple critically praised albums between 2005 and 2012 Read more on Last.fm
