Take a look at all the big bands slated to play at Ozzy's final show, which will feature a reunion of Black Sabbath's original members.

Ozzy Osbourne will come out of touring retirement and reunite with the full Black Sabbath lineup for the first time in 20 years.

The performance, called "The Back to the Beginning," will cap off an all-day event featuring sets from several iconic heavy metal acts.

Scheduled for July 5 at Villa Park, the show will feature Osbourne playing a short solo set, followed by him joining Sabbath for what's described as his "final bow." There will also be performances by Metallica, Slayer, Pantera, Gojira, Halestorm, Alice in Chains, Lamb of God, Anthrax and Mastodon.
