When wife-husband duo Eiko & Koma went to the Reyum Institute of Arts and Culture in Phnom Penh, Cambodia, in 2004, their monthlong visit to teach “delicious movement” workshops developed into a collaboration with young visual arts students, ages 14 to 20. Asking their workshop participants to dance with paintings they’d done resulted in a 75-minute piece, Cambodian Stories: An Offering of Paint and Dance, featuring fiftysomething Eiko and Koma and 11 students, who both dance and complete two paintings onstage. A sand-covered floor gives a sense of the outdoor school, but the bright sunlight in the videotape I watched is something no designer can replicate. The idea is to allow the students to “communicate the memory of . . . inherited pain,” but what struck me was the disparity between the wispy students, who may look sad but have little gravitas, and seasoned performers Eiko & Koma, whose every move carries weight–a sense of the ancient.
