Those masked and robed rockers known as Ghost B.C. have unveiled their highly anticipated video for 'Secular Haze,' the lead single off their sophomore set 'Infestissumam.'

Led by Papa Emeritus II and his Nameless Ghouls, the band set up against a backdrop of purple and black while performing the haunting metal track. The group recently teamed up with director Amir Chamdin in their hometown of Linkoping, Sweden, to shoot the video.

Ghost B.C., who recently modified their moniker in the U.S. due to legal reasons, will make 'Secular Haze' available for all fans online tomorrow (Feb. 19) via iTunes. The song will also be part of the 'Infestissumam' album when it arrives April 9.

Look for the Swedish rockers to cross over to these shores this spring. The band kicks off their North American tour April 14, playing the first of two appearances at the Coachella Festival in Indio, Calif.
