Vezzoli created the narrative of the event: Lady Gaga, in a Frank Gehry-designed hat, would perform on a pink piano painted with butterflies by Damien Hirst while Bolshoi dancers - all in Miuccia Prada-designed costumes - pirouetted in a room decorated with tons of crystal chandeliers, miles of red velvet curtains and walls of Constructivist posters with the images of Lady Gaga and Vezzoli.
