Edith Márquez performs her “Eterna e Inolvidable” concert at the Orpheum Theatre in downtown Los Angeles, presenting a set of Latin-pop songs and classic ballads drawn from her long career. The program spotlights the Mexican singer and actress—who began in the pop group Timbiriche and later built a solo career—and is staged in the Orpheum’s restored, vaudeville‑era theater in the Broadway Theatre District.
