The official website for Ozzfest 2004 (www.ozzfest.com) has revealed the acts that will officially be playing on the festival.

Performing on the Main Stage are: OZZY OSBOURNE, JUDAS PRIEST, SLAYER, DIMMU BORGIR, SUPERJOINT RITUAL and BLACK LABEL SOCIETY.

Appearing on the Second Stage are: SLIPKNOT, HATEBREED and LAMB OF GOD, with rotating guests ATREYU, BLEEDING THROUGH, LACUNA COIL, EVERYTIME I DIE, UNEARTH and GOD FORBID.

MTV.com report: "Sixty trucks and buses carrying 525 crewmembers and as many as 20 bands rolling into town to present more than 13 hours of music on two stages can only mean one thing: Ozzfest is back.

The metal festival's ninth incarnation will find headliner and namesake OZZY OSBOURNE sharing the main stage with JUDAS PRIEST, reunited with longtime singer Rob Halford; SLAYER; Norwegian black metal sextet DIMMU BORGIR; BLACK LABEL SOCIETY; and SUPERJOINT RITUAL, fronted by PANTERA's Phil Anselmo.

Ozzy's participation in the two-month tour is surprising. He sustained severe injuries, including fractured ribs and a broken collarbone that required emergency surgery, in December. Shortly after his release from the hospital, doctors estimated it would take Osbourne six months to recover.

SLIPKNOT, two-time Ozzfest veterans, will headline the second stage, where (unlike the main stage) fans can mix it up in the pit. Fans voting on www.ozzfest.com helped choose the second-stage bands, which include HATEBREED, LAMB OF GOD, ATREYU, BLEEDING THROUGH, LACUNA COIL, EVERY TIME I DIE and UNEARTH.

Additional artists are expected to be announced later.

Ozzfest 2004 will be the first time JUDAS PRIEST tours the U.S. with Halford since he left the band in 1992. The band will begin a brief European trek June 5th in Bologna, Italy.

In 1996 Tim "Ripper" Owens, the singer in a Priest cover band, filled the frontman slot, but last year Halford reunited with original members Ian Hill (bass), K.K. Downing (guitar), Glenn Tipton (guitar) and drummer Scott Travis, who joined the band for 1990's Painkiller.

A new studio album is also expected later this year from the band, which incidentally hail from Osbourne's hometown of Birmingham, England. It would mark the 30th anniversary of their debut, Rocka Rolla.

Twenty-six cities are scheduled for the trek, which starts on the East Coast, heads west to California, then takes the southern route back to wrap up in West Palm Beach, Florida, on September 4. Tickets go on sale February 28th.

Prior to Ozzfest, Slipknot will headline the Jägermeister Music Tour, which kicks off March 30th. The band is scheduled to drop its new, still-untitled album five days earlier.

Ozzfest is one of the summer concert season's most successful outings. The 9-year-old festival has grossed more than $146.5 million and has staged 236 shows for 3.8 million fans. Last year's tour featured Osbourne alongside Korn, Marilyn Manson and Disturbed."
