Why: 14 heavy metal bands join the Prince of Darkness and onetime MTV icon Ozzy Osbourne as Ozzfest enters its 11th year.
Ozzfest kicks off on July 12 in Seattle and ends on Aug. 30 in West Palm Beach, Fla. The main stage will feature Osbourne along with Lamb of God, Static X and Lordi. Playing on the second stage will be Hatebreed, Behemoth and Nick Oliveri and nine others.
Ozzfest is offering its charity to its fans by making tickets free on a first-come, first-serve basis.

Why: Taking over the site of horse racing's Preakness Stakes, The Virgin Festival presents not only some of the most popular bands in the country, but also a host of wild sideshows like Incredibly Strange Wrestling and the Charm City Roller Girls.
As if the presence of the newly reunited Police wasn't enough of a draw, Incubus, Modest Mouse and Matisyahu should be. In all, the lineup includes 40 bands from all genres.
Virgin has also taken nine precautions including clean energy generators and lights and mass transit to make the festival "as close to a zero waste event as possible."
