On their breakthrough sixth album — their last with frontman Bon Scott, who would die after its release, and the first to have the same track listing in every market — AC/DC worked with producer Robert John “Mutt” Lange, and as a result their music wasn’t so much polished as honed to a razor’s edge. They try a few new tricks: “Girls Got Rhythm” is almost funky, and it’s astonishing that the almost Foreigner-esque “Touch Too Much” wasn’t a single. But the title track and “If You Want Blood (You’ve Got It)” are AC/DC classics that hit as hard as anything in their catalog, and the chilling album closer, “Night Prowler,” lets the darkness at the heart of many of Scott’s songs expand like a black rose.
