Cher

Well, this ought to be something... The omnitalented bombshell—a star for nearly five decades—returns to the arenas for her "Dressed to Kill" tour, supporting last year's auto-tune–drenched dance-pop beltfest, Closer to the Truth. The album hasn't yet spawned a "Believe," but lead track "Woman's World" did burn up the dance charts. On the strength of over-the-top razzle-dazzle, not to mention stylistic breadth and sheer megastar wattage, these gigs could be the pop spectacle of the year.
