Priestess is a Canadian rock band formed, in Montreal, Quebec in 2003 by Mikey Heppner (vocals/guitar), Mike Dyball (bass), Vince Nudo (vocals/drums), and Dan Watchorn (vocals/guitar).
Mike Heppner was playing with The Dropouts at the time when three of its members headed to New York to form The Stills. Left on his own, Heppner formed a new band: Priestess. In 2005, the band released their debut album, Hello Master. The release was issued via Indica in Canada and on Ace Fu in the U.S. A major-label recording contract with RCA followed in January 2006.
North American tour dates opening for Dinosaur Jr. followed that spring. Priestess toured with The Sword, Early Man, Diamond Nights, Black Label Society, Black Stone Cherry, Converge, Mastodon and thrash metal pioneers Megadeth as a part of their "Tour Of Duty" tour in June of 2007.
