Black Sabbath — consisting of Osbourne, Geezer Butler, Tony Iommi and Bill Ward — held their star-studded goodbye concert “Back to the Beginning” at Villa Park Stadium in Birmingham, England, where the band was formed in 1968.

Bev Bevan explores the origins of heavy metal music and Black Sabbath's homecoming gig, with interviews and music from Black Sabbath, Judas Priest and Slipknot. As the music stops, fireworks go off above Villa Park as the founders of heavy metal bow out of their unbelievable career.

The "Back to the Beginning" send-off in Birmingham, England, was a fitting finale for the heavy metal band that changed everything.
