For the epic side 4 piece, "Bathory Erzebet", sunn O))) procured a casket then loaded it into a Cadillac Hearse, and locked Malefic inside with only a microphone and a severe sense of claustrophobia.
The result is truly suffocating and disturbing!
The composition of Black One benefits from somewhat extensive live action throughout 2004/2005 bringing more cohesive overall structure to the table. "Cry For The Weeper" and "It Took The Night To Believe" incorporate atonal melodic interplay within their massive skeletons.
Mammoth giants crushing valleys of the drowned. Listeners will still experience core sunn O))) recording fundamentals like being completely overwhelmed by massive subsonic droning guitar riffs.
But with Black One sunn O))) takes it 10 steps below the others by intensely obsessing over making the overall ambience of this album as bleakly crushing, and devoid of light as only they possibly could.
