The big question in early August is whether to seek an opportunity to cool down or to embrace the inevitable sweat. This Wednesday, Bossa offers a fine compromise—the chance to boogie to a lineup of D.C. funk and soul outfits while sipping on a refreshing caipirinha. The night includes sets from Betsy and the Bicycles, a District-formed funk band with original tunes that recently played a sold-out July show on a barge at the Gangplank Marina. Also on the docket: singer-songwriter Lennon English, who’ll play with the New Soul Republic. English creates the kind of rhythmic, percussive music that might play in a movie as someone walks with purpose down a metropolitan street, lost in intent thought. Need a perfect pick-up line to practice for the evening’s festivities? Here’s a free one: “Is that sweat on your shirt or did you just slosh a drink all over yourself?” Betsy and the Bicycles perform with Katie McD and Lennon English and the New Soul Republic at 9:30 p.m. at Bossa Bistro, 2463 18th St. NW. $5.
