“I love dancing,” choreographer, dancer, teacher, and native New Yorker Hilary Easton explains in her artist’s statement. “I love inventing movement, watching it, doing it.” That joy comes through in her work, which has been presented since 1992 at such venues as PS122, Danspace Project, SummerStage, the American Dance Festival, and Lincoln Center Out-of-Doors. Back in October, the New York-based Hilary Easton + Company held the world premiere of their latest work, LIGHT AND SHADE, at the Baryshnikov Arts Center, and they’re bringing it back as part of this weekend’s APAP conference with a special free performance at City Center Studios. The forty-five-minute duet will be performed by Michael Ingle and Emily Pope-Blackman, set to a sound score by Mike Rugnetta, with lighting design by Kathy Kaufmann and costumes by Madeleine Walach. The piece explores the many ways of experiencing intimacy, between the dancers onstage as well as between the performers and the audience.
