After the straight-shooting classic that was “Back in Black,” AC/DC had a bumpy ride for much of the 1980s. They continued to release solid albums, but their sales began to dip after 1981’s “For Those About to Rock We Salute You.” But 1990 was the year the Australian boys reclaimed the hard rock throne with their tough album “The Razors Edge” (hold the apostrophe). That record blasted to Number Two and went multiplatinum in a year when folks like MC Hammer dominated the charts. Produced by the late Bruce Fairbairn (who also worked with Bon Jovi, Poison, and Aerosmith), “The Razors Edge” may not be a classic, but it roars with energy and spunk. Like any AC/DC record, this CD revolves around three themes: sex, drugs (with booze), and rock and roll. The hits on this CD are the rousing “Thunderstruck” and the top 40 hit “Moneytalks,” but other killer cuts are the funny “Got You By the Balls,” “Are You Ready,” the ever-festive “Mistress for Christmas,” and “Fire Your Guns.” Like Robert John “Mutt” Lange, Fairbairn’s production is a bit on the polished side, but it doesn’t compromise AC/DC’s sound. Angus Young’s guitar still rocks, and Brian Johnson’s bark continues to roar in all its shrill glory. I’m not a metalhead by any means, but I know a good album when I hear one. “The Razors Edge” is just that.
