While most of us were mastering the art of cursive and sibling torture at age nine, Priscilla Ruiz (a/k/a P-Star) was flooring audiences in New York City clubs with her spectacular rapping skills. Documentary P-Star Rising, playing tonight as part of the Rooftop Films series, follows Ruiz’s ascending career over four years, tracking how the girl’s success transforms her struggling family—from a Harlem shelter to a four-bedroom apartment, from subways to chauffeured SUVs—and the complications that ensue. Through director Gabriel Noble’s multidimensional lens, P-Star’s manager-father is both a queasily ambitious stage parent and a single father who wants the best for his children—and Ms. Ruiz a teenage girl faced with the responsibility of supporting her family, while seeking her own independence. P-Star will give a live performance before the film, and Noble will be on hand to answer questions after.
