The recent relationship between the Anacostia River and art hasn’t been great, but a new exhibition at Anacostia’s Vivid Solutions Gallery, “Confluence: Considering the Anacostia,” offers the star-crossed waterway a chance for a fresh start. Piper Grosswendt (the gallery’s associate director) and local photographer Bruce McNeil put out a call for photographers and asked them to respond to the river and its surroundings. The exhibit, timed to coincide with the inaugural Anacostia River Festival, features work by McNeil and three other artists—Becky Harlan, who focuses on people who use the river; David Allen Harris, who specializes in landscapes; and Krista Schlyer, who trains her lens on wildlife. McNeil, for his part, documents the journey the river takes from its origins in Sandy Spring, Md., to its confluence with the Potomac River.

Saturday: The Auto-Tuned vocals of Côte d’Ivoire’s Serge Beynaud are the first sign that his dance music takes a more contemporary approach to the traditional West African grooves of yesteryear. Beynaud’s 2014 release Talehi features tunes with frenetic rhythms and guest rappers, as well as ones with slower, sappier melodies. His croons over saccharine guitar strumming, drawn from the French-Caribbean zouk style, may have helped enhance his heartthrob status, but funky, syncopated tracks like last year’s single “Okeninkpin” are his chefs d’oeuvre.

Sunday: Before Google Maps sent personalized routes to our phones, people used actual maps to get around. Although those paper documents were fine for traversing continents with notable physical features and landmarks, they weren’t nearly as effective for crossing vast, featureless oceans, especially when navigators had to keep piloting the ship after dark.  The risk was so great that in 1714, the British government created the Longitude Act, which offered a reward for anyone who could find a way to determine longitude at sea. Now, an exhibit at the Folger Shakespeare Library, created by the staff at Greenwich, England’s National Maritime Museum, presents the different solutions they came up with through more than five decades of study and experimentation. Read more >>> The exhibition is on view Mondays through Saturdays 10 a.m. to 5 p.m. and Sundays noon to 5 p.m. at the Folger Shakespeare Library, 201 East Capitol St. SE.
