Isabel Alarcón and Alejandro Molinero star in “Pulso,” a production that interprets flamenco as a shared heartbeat and as a convergence of tradition, the body, and the present. The show is built around the intensity of the rhythm and the intimacy of the tablao, with Juan José Ramos on guitar and Antonio de Manuela on vocals serving as its musical backbone. Daniel Ramos, Paca Rodríguez, and Rubén Puertas round out a program that invites audiences to experience flamenco in its most direct, emotional, and vibrant form.
