If Princess Superstar seemed uncharacteristically quiet since her 2001 breakthrough, “Bad Babysitter,” the fruits of her focus have arrived. As her handle betrays an obsession with fame, My Machine is an opera of self-indictment that envisions her own desire taken to science fiction extremes. Backed by an army of “duplicants,” Superstar corners the market on fame in the year 2080. Problems ensue. Thankfully, the 77 minutes include funny (“Quitting Smoking Song”), horny (“Hoochie Koo”), dancey (“The Happy”) numbers that have nothing to do with the narrative. She’s the missing link between Madonna and Peaches, with a wit to match her ego. She rates acclaim without resorting to cloning herself, making the story that much more compelling.
