Creating art can be a lonely gig. Those breathless nights of genius that leave you dripping in acrylic paint may feel like a group project—until you realize the only group involved is the chorus in your head. D.C.-based artists Nathan Manuel and D. Billy have solved the age-old “I need someone to play with” conundrum by making art together for their show, “Points of Departure.” The mixed-media piece Title Bout is a good example of the pair’s style: Cartoonlike drawings of work shirts line the left side of the canvas; ranch-style homes hang suspended over the ground on the right. A fat, sparkly diamond ring floats up to the clouds. Rain falls from one of the clouds, so a house “speaks” a comic-book picture of an umbrella. A criticism of mainstream values and suburban ideals? Ask the house from 2 to 7 p.m. (through Dec. 11; see City List for other dates) at the District of Columbia Arts Center, 2438 18th St. NW. Free. (202) 462-7833.
