Set to take place July 26 at McMahon Stadium, the show will feature headlining performances from Osbourne and Judas Priest [ tickets ], as well as sets from System of a Down frontman Serj Tankian [ tickets ], Cavalera Conspiracy, Shadows Fall [ tickets ], Voivod, Testament [ tickets ], 3 Inches of Blood, Priestess and Zimmers Hole. Additional acts are expected.

Tickets will hit the box office Saturday via Ticketmaster and Unionevents.com, with prices ranging from $49.50 to $119.50 plus applicable service charges, according to a press release. (Ticketmaster is LiveDaily's parent company.) The venue's floor will house general-admission ticketholders, while the stands will feature assigned seating, according to organizers.

Osbourne will hit the stage with his longtime guitarist Zakk Wylde, drummer Michael Bordin, bassist Rob "Blasko" Nicholson and keyboardist Adam Wakeman. The heavy-metal icon continues to support his latest album, last year's "Black Rain."

Judas Priest's most recent release is 2005's "Angel of Retribution," the group's first set to feature original lead singer Rob Halford since 1990's "Painkiller." Halford and company plan to release a new set this year titled "Nostradamus," but a street date hasn't been announced.

Details for this year's Ozzfest outing remain under wraps, but Osbourne is expected to again headline the tour.
