Well, this was just kind of an awesomely goth-y mess. Or, to put another way: a pretty awesome version of an Evanescence video! Perry, dressed in a flowing black gown, began her performance of "Dark Horse" by singing from inside a crystal ball, the stage set a spoooooky mess of dead trees, around which back-up dancers carrying witches' brooms cavorted. Later, having escaped from the sphere, Perry was greeted by a dark metallic-looking puppet horse. Then Juicy J came out to deliver a verse, dressed in a dark suit, standing eerily still — he came off like an ultra-suave grim reaper. The performance may not have achieved the same grand guignol energy of Nicki Minaj's exorcism extravaganza from the 2012 Grammy telecast, but it entertaining as, um, hell.
