Ozzfest

Annual festival that was ultimately started by Ozzy Osbourne's wife, Sharon Osbourne, in retaliation against Lollapalooza management, whom would not put Ozzy on the Lollapalooza line-up because he was not considered "cool" in the alternative world. Ever since 1996, this annual tour has increased in popularity, bringing metal bands such as Megadeth, Pantera, Fear Factory, and, of course, Ozzy and Black Sabbath. Due to the uprise of nu-metal in recent years, this festival seems to get more "commercial" every year.
