Ozzfest, the long-running touring metal package, is rumored to be morphing into a two-day "destination festival" in Dallas. There has been no official word yet on what format Ozzfest will take or who will be on the bill.The rumors come in the wake of this year's arrival of the metal-oriented Rockstar Energy Mayhem Tour, which will play 30 North American amphitheaters during July and August, the time when Ozzfest is traditionally making its rounds. Last year's Ozzfest offered free admission, with fans acquiring tickets mostly through sponsoring web sites. But the acts were not paid either, which resulted in a decidedly less than impressive main stage lineup. The Mayhem trek has already robbed Ozzfest of two potential main-stage heavyweights in DISTURBED and SLIPKNOT, with fan favorites DRAGONFORCE and MASTODON also taking part in the Mayhem tour. OZZY OSBOURNE is likely to headline Ozzfest as a solo act again, since his BLACK SABBATH bandmates are busy with their HEAVEN AND HELL offshoot. The Mayhem tour is being co-produced by Kevin Lyman, who has the successful Warped and Taste of Chaos packages on his resume.
