Crowleymass was an EP released in 1987 by the English group Current 93, led by David Tibet. Crowleymass originally appeared on a 12” vinyl record through Maldoror and was later reissued in 1997 on CD format through Durtro, the record company owned by David Tibet. This reissue contained a bonus track titled “I Arise”.
With four songs, this record was produced by Icelandic renowned musician Hilmar Örn Hilmarsson and had the collaboration of guitar player Guðlaugur Kristinn Óttarsson; former Strawberry Switchblade backing vocalist Rose McDowall, J. Sen and Nyarlathotep's Idiot Flute Players.
With a more danceable orientation as compared with previous works (excepting the uncharacteristically heavy metal-like "I Arise"), Crowleymass is a very particular release and is considered as an object of cult by gothic rock and industrial music followers.
