One of the most legendary heavy metal bands of all time is reuniting.

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

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.
