Unholy Matrimony is a solo musical entity from Switzerland created in 2000 by Vladimir Cochet of Mirrorthrone and Weeping Birth. The music evolves from radical Black Metal without concession and blends elements of death metal and visceral ambiance that is unrivaled in extreme music today. Unholy Matrimony's new album "Croire, Décroître, the follow up to their "Misologie" album released in 2003. A colossal cacophony of beauty and a fierce black metal framework which could be viewed as a harsher Mirrorthrone is only a fraction of what to expect.
