In the past, people complained that "it's not Ozzfest without Ozzy." Well, he's back this year, and if you were lucky enough to get tickets, you know it's a free show. While the "Prince of Darkness" is headlining the show, the supporting acts aren't too shabby, either. Lamb of God, Static-X and Hatebreed are some of the other names you'll see. You can also catch Cthonic on the second stage -- they're a metal band from Japan with an affinity for face makeup. Practice your devil horns and head out. 12 p.m. Verizon Wireless Amphitheatre, 707 Pavilion Blvd. 704-549-5555. www.livenation.com.
