Multi-night headlining runs are nothing new in Las Vegas, but the Hard Rock Hotel has shaken up the concept by bringing in bands—Mötley Crüe (twice), Def Leppard, Guns N’ Roses (twice) and soon Kiss—for a dozen-ish shows at a time. We’d like to see the formula applied to acts outside the ’80s hair/glam-rock genre, because we’re itching to see a favorite group two or three or, hell, six or seven nights straight.
