In a feat of astonishing ambition and virtuosity, D.C.s GALA Hispanic Theatre, one of the nation’s top Spanish language cultural centers, has managed to produce a complex, difficult, popular Broadway musical in Spanish, most appropriately about the life of diva and Cuban icon Gloria Estefan. “On Your Feet’ is a tour de force! GALA Theatre has used every possible resource within its reach to provide for a first rate, top of the line, exciting song and dance show with live musicians, exquisite voices and a dance ensemble made for Radio City Music Hall. All told, it is a production of extraordinary breadth and sophistication.
