WITNESS: The Tour is an imaginative trip from outer-space to inner-space, from the planets to the bottom of our oceans, and a musical journey through Katy Perry’s biggest milestones and mega-hits right up to her latest album. The dramatically original staging means that there isn’t a bad seat in the house, when Katy brings out her band and dancers, along with all the bells and whistles.
