Here's eight things we still can't believe happened at the Back to the Beginning Concert. Other than the fact we can't believe that two of us at Loudwire made it out to Birmingham for this historic event, there's more than a handful of particular moments and things in totality that really are mind-blowing.

Black Sabbath reunites for their final show with the emotional ‘Back to the Beginning’ concert, marking the end of a legendary metal era.

Ozzy Osbourne and Black Sabbath's farewell show featured performances from bands including Tool, Guns N' Roses, and Metallica.

And while it was an important moment for all of us, it was an equally important moment for a number of houses and hospitals in the Birmingham area, as it turns out the event generated nearly $200 million for those causes.

Nearly every rocker that took the stage at Ozzy and Black Sabbath's farewell performance had something to say about them afterward.

Guns N’ Roses Back to the Beginning concert was nothing short of spectacular. The band performed a six-song set at Ozzy Osbourne’s farewell show, which included four Black Sabbath covers.
