This year's Ozzfest, being held August 9th in Dallas, will feature an all-star metal tribute to slain Pantera and Damageplan guitarist "Dimebag" Darrell Abbott. The participants include Metallica's Kirk Hammett, Slayer's Kerry King, Jerry Cantrell of Alice In Chains and Anthrax's Scott Ian. Bob Zilla of Damageplan and Dimebag's brother Vinnie Paul will also take part in the event, which was orchestrated by Abbott's partner Rita Haney. The set is expected to pull strongly from Pantera's catalog. Dimebag Darrell, who called Dallas home, was shot and killed onstage by a deranged fan during a concert in December 2004.
