At New York’s Hammerstein Ballroom on Saturday and Sunday to play two sold out shows, attended by 7,000 concert goers, Miss Hatsune Miku was the headliner, coquettishly shimmying across the stage — sending the audience into frenzied screams, their glow sticks raised in a unified sway. The performer’s buoyant teal pigtails, pleated miniskirt and coy lyrics drew amorous howls. But such entrancement wasn’t aimed at a human performer. Hatsune Miku, a hologram pop star from Japan touring North America, only human quotient is the community of fans who conceive her. Her voice is computer-generated and her song catalogue is entirely the creation of everyday people — a phenomenon known as “vocaloid.”

Miku has spurred interest from the fashion world. In 2013, Marc Jacobs was named as the digital wardrobe designer for her virtual opera tour, “The End.” Jacobs clothed Miku in a monochromatic checkered outfit inspired by designs from his spring 2013 collection for Louis Vuitton. Earlier this month, Riccardo Tisci gave the vocaloid a sartorial makeover in his gothic haute couture.
