Watch Black Sabbath's Final Performance of "Children of the Grave"

Teaser comes from band's upcoming documentary 'The End of the End'

Later this month, Black Sabbath will premiere Black Sabbath: The End of the End — director Dick Curruthers' documentary detailing the icons' final concert, which was held last February in their Birmingham, England, stomping grounds. After sharing a trailer for the film – which will be screened in theaters around the world for one night only, on September 28th – Ozzy Osbourne and Co. have teased the cinematic action further, with a brief glimpse at their (literally) fiery final performance of "Children of the Grave." Watch now, and for a list of theaters participating in the Black Sabbath: The End of the End screening event, check out the film's official website.

But wait – there's more! The day after The End of the End plays theaters (September 29th), Black Sabbath will keep the victory lap going with The Ten Year War, the titans' highly anticipated box set. A collector's dream, the limited-edition release collects remastered editions of the band's first eight LPs, two rare 7-inches, a cross-shaped USB stick (which you can also rock as a necklace), a hardcover book with photos and essays, a reprinted poster and much more.
