52. Def Leppard, 'Pyromania' (1983)
"We wanted an album that sounded the way Steven Spielberg's movies looked," Def Leppard vocalist Joe Elliott has said of the band's vision for Pyromania. To achieve that end, the band and uber-producer Mutt Lange (AC/DC, the Cars, Shania Twain) spent nine months and nearly a million dollars recording the Sheffield heavy-metalists' third full-length, employing the latest synthesizers (courtesy of "She Blinded Me With Science" star Thomas Dolby), bleeding-edge recording techniques like the use of drum samples, and heavily stacked, pitch-perfect vocals to bolster the album's unprecedentedly massive sonics. But ultimately, it was Def Leppard's evolution from a rough-around-the-edges hard-rock band into a unit capable of seamlessly melding heavy riffs with anthemic, mainstream-friendly melodies that pushed Pyromania into the sales stratosphere. The summer of 1983 saw the album moving more than 100,000 units per week, and deservedly so: Songs like "Photograph," "Rock of Ages" and "Foolin'" didn't just pack one hell of a wallop; they were world-class earworms.
