Brandon Morse’s video installations are atmospheric—not in the moody sense of the word (although they are that) but rather in the way that his works convey complex patterns and stormy algorithms. Weather isn’t so much a theme as a function in Morse’s work, so it’s fitting that his latest installation project, “In This Convex Hull,” is at a planetarium. Planetarium videos usually depict the expansiveness of space and the impossible vastness of the solar system, but if Morse’s past work is any indication, his video will be directed inward, not outward: a more localized space, a more delineated system, and an altogether more disorienting experience.

This truth is center stage in Washington Improv Theater’s latest production, POTUS Among Us. Since 2004, the comedy ensemble has put on quadrennial election-year simulations. Over the course of this show’s 90 minutes, an initial group of five candidates will be narrowed down to two, and, eventually, one winner. Along the way, scandals, breaking news events, and other attacks are lobbed at the eccentric candidates, with the winner emerging triumphant from the bizarre and nasty fight.

Sunday: Rock ’n’ roll from the American South often tries to reckon with “the duality of the Southern thing,” a concept most recently brought up on the Drive-By Truckers’ latest album, American Band. A Spartanburg, S.C., native of Trinidadian descent, Adia Victoria doesn’t have the privilege of knowing that duality. She only knows the “thing.” “I don’t know nothin’ ’bout Southern belles, but I can tell you somethin’ ’bout Southern hell when your skin give ’em cause to take and take,” she sings on “Stuck in the South.” Chugging, swampy guitars burn through her debut, Beyond The Bloodhounds. But there is no love lost for white Southern nostalgia. Read more >>> Adia Victoria performs with Sir E.U. at 9 p.m. at DC9, 1940 9th St. NW. $12–$14. (202) 483-5000. dcnine.com. (Justin Weber)
