Local fans of the annual Smithsonian Folklife Festival take note: the dates and themes for this year’s festival were released today. From Wednesday, June 24, through Sunday, June 28, and again from Wednesday, July 1, through Sunday, July 5, you’ll be able to explore the following along the National Mall: “Giving Voice: The Power of Words in African American Culture,” “Las Américas: Un Mundo Musical/The Americas: A Musical World,” and “Wales Smithsonian Cymru.” So expect plenty of staged readings of historical African American texts, mariachi, marimba and chanchona musical performances, and um, Welsh cooking (ick?), this summer.
