Those horns kick in, and we’re transported into breathtaking music-video territory. Stop-motion animation was the name of this new game, with Peter Gabriel allowing himself to lie under a sheet of glass for 16 hours while filming “Sledgehammer” one frame at a time. Director Stephen R. Johnson is clearly having the time of his life, matching up lyrics to images Gabriel sings about “a bumper car bumping,” and that’s what happens to our hapless star. It’s one of MTV’s most important videos ever: not only did it win nine Video Music Awards in 1987 (a feat still unsurpassed); it’s also the most played clip in the history of the channel. As for the people who provided the claymation, pixelation and stop-motion animation they were called Aardman Animations. What became of them? They would go on to make a certain Oscar-winning series of shorts about Wallace and Gromit.
