Leviathan is an experimental/ambient black metal ban formed in 1998 by main man Wrest. In Leviathan, Wrest records and plays all instruments including vocals entirely on his own. Additionally, Wrest has collaborated with the band Sunn O))), and is an active member of the U.S. black metal supergroup Twilight. He has stated in interviews that he has been playing drums longer than any other instrument and that the drums are his instrument of choice. Wrest also plays and records everything in his other project Lurker of Chalice. Regarding his writing, Wrest says that "...lyrics are important and also very hard for me... at times, the way things come out in words sounds like nonsense. I don't consider myself a poet by any means."
