Original Singer: Rob Halford
Reason for Departure: Halford split in 1992 after years of tension to form thrash metal band Fight.
The Replacement: Tim "Ripper" Owens
After a few years of dormancy following Halford's departure, the band returned in 1996 fronted by "Ripper" Owens, a superfan who previously performed in a Priest tribute band. His story was (loosely) portrayed in the Mark Wahlberg film "Rock Star." The band has since reunited with Halford and, fresh off a performance on the "American Idol" finale, is prepping for a new album in 2012. —Jeff Royer
