In her early 20s, the Belgian choreographer Anne Teresa De Keersmaeker created two dances that remain among her most distinguished: “Fase, Four Movements to the Music of Steve Reich” (1981), for two women; and “Rosas Danst Rosas” (1983), for four. The last time she brought these minimalist masterpieces to New York, as part of the Lincoln Center Festival in 2014, Ms. De Keersmaeker, then 54, was among the performers onstage, joining dancers in their 30s and 40s.

Age matters here, because what stands out about the latest revival of these works, presented in a two-week engagement at New York Live Arts, is the sense that Ms. De Keersmaeker has handed them off to an eager, energetic new generation. The dancers who have inherited them — Laura Bachman, Yuika Hashimoto, Laura Maria Poletti and Soa Ratsifandrihana — all joined her company, Rosas, in 2016. The youngest is 25; the oldest, 28.

As if having accepted a mission, or a gift, they instill both “Fase” (performed last week) and “Rosas Danst Rosas” (which opened on Tuesday) with youthful pride and attack. At their finest, they shed diligence for abandon, losing themselves in the material and making it their own.

Ms. De Keersmaeker, who is now busy choreographing the coming Broadway production of “West Side Story,” has said that with these early works, she was trying to find, quite simply, “movements that I liked.” That search led her deep into repetition, a defining feature of “Fase” and “Rosas.” I n a video about the creation “Fase,” she recalls appreciating Steve Reich’s music for his use of “a minimum of material in a maximum way.”
