By 1985 Peter Gabriel had released four solo albums, all of them titled Peter Gabriel. Nowadays most people subtitle them based on the cover artwork (e.g. Peter Gabriel (Scratch), Peter Gabriel (Melt), etc.), and while I suppose that amused Gabriel, it did not amuse the folks at his label.
They pushed back hard to get him to take marketing his work more seriously, so he came up with a title that wasn’t really much of a title: So. But Gabriel had, perhaps because of his work on Birdy, had caught on to the worldbeat sound, and incorporated it into the compositions on So. In addition, he got ridiculously lucky with some very creative people to direct and produce the videos that supported the singles. “Sledgehammer” and “Big Time” in particular were very MTV-friendly, and all of a sudden Gabriel is himself on his way and making it in the Big Time, with So going Top Five around the world.
And the fact that the “In Your Eyes” single was a tonal changeup from most of the other singles (“Don’t Give Up” notwithstanding), meant that Peter Gabriel was being taken more seriously as a versatile performer than he was previously, when he was thought of largely as a cult favorite.
I didn’t promise this during the show, but I’m throwing it in here anyway. Here’s the source material for some of the “In Your Eyes” video.
