Leviathan is an American black metal solo project that started in 1998 by Jef Whitehead under the pseudonym Wrest. On all Leviathan albums, Wrest records and performs vocals on his own. Despite having early problems with the release of Massive Conspiracy Against All Life, it was released March 24, 2008 in Europe and March 25, 2008 in North America. Additionally, Wrest has collaborated with the band Sunn O))), and was an active member of the U.S. black metal supergroup Twilight from its formation until it disbanded in 2014. 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 played and recorded everything in his other project, Lurker of Chalice, which released two demos and one full length album in 2005 before dissolving that project. Whitehead also writes all the lyrics for Leviathan but has recognized that "I don't consider myself a poet, by any means."
