Peter Gabriel released “So,” the biggest hit of the oft-inscrutable English art-rocker’s now-47-year career. The album’s deluxe 2012 reissue includes primitive versions of each of its nine songs: “Sledgehammer” was the single that went to No. 1 in the United States, but “Big Time,” “Don’t Give Up” and the ballad “In Your Eyes” — immortalized when John Cusack played it from a boombox held over his head in Cameron Crowe’s anxious-youth romantic comedy “Say Anything” — were all chart-climbers, too.
