In a world filled with change, there's something profoundly reassuring about AC/DC. They're like a James Bond film -- a winning formula, unvarying, but packed with loud noises, big explosions and stuff about busty lasses. You go in knowing what to expect and you're never disappointed. The boys are as ribald and rockin' as ever on their newest album, AC/DC's 17th to date. Never ones to pass up an opportunity for an oblique phallic reference, they've called it Stiff Upper Lip.
