Jerome Robbins’ Noh-inspired dance piece follows a male figure (New York City Ballet principal dancer Joaquin De Luz, who retires this fall) through scenes from his youth, each moment of his journey conveyed in studied, deliberate articulations. Framed by lunar and seasonal transitions, this rarely performed work—beautifully reimagined for BAM’s Fishman Space stage by director-choreographer Luca Veggetti—is a rumination on experience and memory, named for the beloved Long Island town. Featuring composer Teiji Ito’s score for six musicians—prominently featuring the shakuhachi, the 13th-century flute played by Buddhist priests—and dancers from Conservatory of Dance at Purchase College, SUNY, Watermill is a study of time that still quietly resonates nearly a half-century after it was first staged.
