Priestess was a Canadian hard rock/stoner rock band formed by singer/guitarist Mikey Heppner in Montreal, Quebec in 2002, comprising Heppner, singer/guitarist Dan Watchorn, singer/drummer Vince Nudo, and bassist Mike Dyball. Priestess were considered one of the most important bands in the early millennial "retro rock" movement, although they denied intentionally attempting to emulate the sounds of classic rock bands such as Black Sabbath and AC/DC, whom they idolized and to whom they were frequently compared.
