Jack Black may be one of the biggest comedic actors of all time, but he’s also a massive rock fanatic. When he wasn’t on the big screen, he used to make music as Tenacious D and back up a variety of different bands.

Now, in honor of the late Ozzy Osbourne, the actor and comedian performed as ‘Jack Sabbath’ at the Power to the People festival in Columbia, Maryland. There, he brought out actual Black Sabbath bassist Geezer Butler for a cover of the classic “War Pigs”. Check out the blockbuster cover down below:
