This long weekend brings days full of solemn tributes, parades and music at Arlington National Cemetery and a concert on the Capitol’s West Lawn. (We have a roundup of events across the area, not all of which are also included in this column.) But it’s also the unofficial beginning of summer, with the multiday D.C. Black Pride Festival; a house music party with Crystal Waters in Franklin Park; the Funset’s big dance party at the Dew Drop Inn; blues music until the wee hours at Glen Echo Park; and events celebrating Asian American and Pacific Islander Heritage Month, including a trivia night at the Smithsonian and a night market atop Union Market.
