The Upper Crust
Wikipedia says, "The Upper Crust is an American hard rock band from Boston, Massachusetts. The members adopt the personae of 18th century aristocratic fops and sing songs from that perspective. They use titles of nobility, wear powdered wigs and period costumes, and maintain a snobbish attitude both during live performance and on their albums. The members say that their guiding philosophy is 'if not great and excellent, then debauched.'"
