"Opus Diaboli" is a commemoration of Watain's 13 year Anniversary and the first ever DVD documentation of the Swedish Black Metal legends! a visual and audio documentation of their ceremonial concert performance in Stockholm and the long years of physical, intellectual and spiritual work leading up to it. An epic DVD/2 CD 90 minute journey into the forbidden realms of wild hearted Satanic Metal and a manifest of a unique band that truly have chosen a path that few have ever dared to tread upon.
