The Washington Project for the Arts’ newest exhibit, “Hostile Witness: Taking the Methods of Media and Surveillance into Your Own Hands,’’ is designed to ask the viewer “What did you see?’’ “What are you going to do about it?’’ and “Who controls the information?” A very multimedia show, pieces range from a 4-foot-by-4-foot glue trap by Michael Udris to Constantine Roumel’s looped footage of R. Bud Dweyer shooting himself before a press conference. Tonight the gallery celebrates the show’s opening with the first of two accompanying performances. Among those appearing are poets/performers Silvana Straw, Kenny Carrol, and the ensemble DIASfORA examining the exhibit’s themes through spoken word, movement, and music. At 8:30 p.m. at the Central Armature Annex, 625 D St. NW; Eric Cheevers screens his 12-minute film Connie Sellecca’s Recipe, and Erika Doyle and Karma Johnson perform a slide-illustrated interactive piece at 8 p.m. on Dec. 15 at the WPA Main Gallery, 400 7th St. NW. $4. (202) 347-4813. (Maria Ware)
