The original line-up of heavy metal legends Black Sabbath, including Ozzy Osbourne, will play together for the first time in 20 years at a one-off concert on July 5 in Birmingham, England, organisers said on Wednesday.

The original Black Sabbath lineup, featuring Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward, will perform at the “Back to the Beginning” concert on July 5 in Birmingham, England.

Sharon Osbourne gave an update on how Parkinson’s disease has impacted husband Ozzy Osbourne’s legs as the musician prepares to reunite with Black Sabbath in July for his final concert.

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.

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

Black Sabbath is reuniting for one more show to celebrate Ozzy Osbourne's final concert in Birmingham, England on July 5.

Black Sabbath and Ozzy Osbourne's swan song boasts a stacked metal lineup unlike any other single-day festival of this century.

The all-day event will also feature a host of major metal bands including Metallica, Slayer and Alice In Chains, with more names to be announced shortly.

Disturbed’s David Draiman told The Jerusalem Post he "can’t wait to celebrate the career of the Godfather of Metal."
