Let the madness begin!” bellowed a mischievous Ozzy Osbourne from his bat-and-skull encrusted throne in front of a sold-out Villa Park in Birmingham, England. The Prince of Darkness had finally taken to the stage after a marathon of legendary metal bands paid homage to his life and work throughout the day for his and Black Sabbath’s Back to the Beginning concert on Saturday,

Ozzy Osbourne and Black Sabbath have gone out with a bang at what they say will be their final gig, in front of 40,000 fans and supported by an all-star line-up of rock legends who have been influenced by the founding fathers of heavy metal.

The full lineup, which kicked off at 1 p.m. BST, featured an all-star cast of performers. Alongside Black Sabbath, the day also saw performances from Metallica, Slayer, Guns N' Roses, Tool, Pantera, Anthrax and more.
