The workings of internal organs might come to mind when watching experimental flamenco dancer Rocío Molina contort and pulse her body onstage; she exudes a feral abandon that most people hide beneath pleasantries and skin. In this documentary, which follows her for eight months as she prepares for a show in Paris, director Emilio Belmonte attempts to unpack her process. This includes observing Molina’s “impulsos”—what she calls the urges she feels in her body before improvised movements form—and, in a sense, dancing to keep up: moving the camera along the floor with her as she slides through white ruffles and shooting from above as she swirls blood-red paint from her skirt across the stage. Witnessing Molina’s outpour is so transporting that when Belmonte cuts to downtime or interviews with others, the transitions can feel disruptive. An exception is a surprising conversation with Molina’s mother in Málaga, Spain, in which she describes her fear when watching her daughter dance: “She looks for this extremity, this limit she must cross to stop being herself and become this monster.” What an outlet. In Spanish with subtitles.
