No, make that one of the greatest drum workouts ever, period.
Bill Ward is the drummer. The track is War Pigs, from Paranoid, the immortal heavy metal opus by Black Sabbath.
What, you won't listen to Sabbath? Why not? They're another one of those groups that you're embarrassed now to admit you used to like, but they didn't become famous just because of all the occult trappings.
Sabbath are, after all, credited with being among the pioneers of heavy metal. They also had a few other things going for them, including: a solid rhythm section; a pretty original guitarist; and a very original singer.
Back to War Pigs. If there's a 4/4 fill in existence that Bill Ward didn't play at some point in this track, I'd like to know what it is. He also plays excellent backing on the two extended guitar solos by Tony Iommi.
The best way I can think of to describe his sound is this: he is tight without sounding tight. Same goes for bassist Geezer (real given name Terrence) Butler.
I heard War Pigs on the dinosaur rock radio station. If you don't want anyone to know you listened to it, you can wait for it to come on while you're in the car by yourself (they play it pretty regularly, I suspect). If you're not concerned about the overlords of the internet knowing you listened to it, it's easy to find on Spotify.
If you dare to listen to it on the internet, listen to the whole album. Just ignore (or chuckle at) the lyrics, and groove on the sound of what was, at its roots, a great blues rock band, while Ozzy mesmerizes you with his barely controlled scream.
