Last year, New York City Ballet wowed fans by hiring its youngest choreographer ever, the then-18-year-old Gianna Reisen, to make a ballet for its Fall Fashion Gala. For this year's gala, held September 27 at Lincoln Center's Koch Theater, Reisen will be back alongside NYCB first-timers Kyle Abraham and Matthew Neenan. All three will present world premieres. Reisen, a former student at the School of American Ballet, is now an apprentice at Dresden Semperoper Ballett. "Living, dancing and choreographing in Europe has given me a set of tools that I could never throw away," she says. Reisen will work with a cast of 18 dancers to a score by John Adams, and will incorporate set pieces onstage. "I plan to tell more of a story this time around," she says.
