Imagine if the surroundings in “The Wizard of Oz”’s Munchkin Land fused with the backdrop of “Alice in Wonderland” and you might have the Katy Perry “Witness” tour.

It's a delightful spectacle to behold – from the five-piece band dressed in cupcake-frosting pink to the see-sawing lighted cubes to the massive eye-shaped video screen blasting gorgeous images of Patrick Nagel-inspired art and swirly imagery.

Of course, such a well-designed presentation doesn’t leave a fraction of space for spontaneity (save for a well-intentioned, but momentum-killing phone call to Perry’s mom, Mary). But when every shoulder shrug and crossed leg is delivered with such polished precision, you really can’t help but fall into this highly stylized production.

Still, despite the award-worthy production, Perry’s Tuesday night performance at Philips Arena felt a bit sluggish at times.
