“Peter Gabriel is one of the great sonic explorers of pop-music history, a classic restless spirt whose wanderings have always demanded attention,” (Stereogum). “Gabriel has a decades-long history of big, bold gestures. He was early on all sorts of things — art-rock theatricality, massive drum-sound reverberations, the pop-music embrace of various different forms of African music. He championed worthy global political causes and worthy global musicians, exposing them to people who would’ve never otherwise known much about them. Few artists have had as much effect on the texture of pop music, on the way that you can turn songs into complete sonic environments. So naturally, the one time Peter Gabriel hit #1 in the US, he did it with a janky, digital white-soul song about his dick. That’s pop music for you.
(1986’s) ‘Sledgehammer,’ Peter Gabriel’s big hit, is one of the many, many songs that owes a great deal of its success to its music video. That’s another thing that Peter Gabriel embraced early: The warping, convulsive possibilities of music videos as an art form. Gabriel’s ‘Sledgehammer’ video is one of the all-time masterpieces of the medium … By some estimates, ‘Sledgehammer’ is the most-played video in the entire history of MTV.
… Gabriel’s early singles did pretty well on the UK charts. In the US, Gabriel was less of a presence. A couple of tracks charted: 1977’s ‘Solsbury Hill’ at #68, 1980’s ‘Games Without Frontiers’ at #48. But Gabriel was more of a culty, esoteric figure until the advent of MTV made him harder to ignore. 1982’s ‘Shock The Monkey’ reached #29, largely on the strength of its memorably freaked-out video. Still, a song like “Sledgehammer” represented a real and self-conscious turn towards the pop mainstream … Gabriel has acknowledged that ‘Sledgehammer’ owes much of its pop success to the video … But on its own, ‘Sledgehammer’ is a charmingly goofy dance-pop song with production that makes it sound fucking huge, like a spaceship taking off. Even without the video, it would’ve been a hit. Even without the video, it’s a lot of fun.”
After an intro in Eb minor, the verse shifts to Eb major (with the major third prominently placed as the vocal melody’s opening note) at 0:52. At 3:11, there’s a return to the original key for an interlude, with the vocal re-joining the mix at 3:41 for the bridge.
