Trivia / Sunn O)))

• All-Star Cast: On top of being a collaboration between Sunn O))) and Boris, Altar also features Jesse Sykes, Kim Thayil, and every member of Earth, making it perhaps the ultimate crossover in drone doom.
• Enforced Method Acting: Malefic's shrieked, hyperventilating vocals on "Báthory Erzsébet" are the product of the band shutting the deeply claustrophobic guest singer in a coffin with his mic.
