The venerable and vivacious Ballet Hispánico, founded in 1970 by Tina Ramirez, makes its Northrop debut (and opens this year’s Northrop dance season) with a program by Latina choreographers. They may not be household names yet, but their work is indelible. In “Con Brazos Abiertos,” the dancers animate choreographer Michelle Manzanales’ narrative about navigating the worlds of Mexico and the United States while growing up in Texas. Belgian-Colombian dance maker Annabelle Lopez Ochoa’s “Sombrerísimo” focuses on the company’s male dancers, who move with sensual and technical ferocity. In “3. Catorce Dieciséis,” by Tania Pérez-Salas, the circularity of life and pi are explored. Now under the direction of Eduardo Vilaro, the company continues its trajectory from dance school and community-based troupe to dance company of international acclaim—all while staying close to its roots.
