Diehard District Flea shoppers disappointed in the quick departure of the weekly market will rejoice in the reincarnation of the Lot at Atlantic Plumbing as an outdoor music venue: Paperhaus and Outputmessage will front a free show at the soon-to-be-redeveloped space on Saturday. Outputmessage will play from a new album described by the artist as “a journey through space”—DJ/singer/producer Bernard Farley entertains other-planetary life in “Goldilocks Zone,” a song about a star believed to be ideal for human life, and “Satellite,” a rhythm-locked horn-bass-synth jazz piece that finds Farley singing, “In time and space, we go forward/In the darkness, we find our place.” The local rockers of Paperhaus, meanwhile, have turned highly imaginative in a recent homemade music video for “Helicopters,” shot in the band’s Petworth stomping grounds, in which frontman Alex Tebeleff falls asleep after a barista shift and dreams of a cardboard gun- and helicopter-ridden D.C. where he fights for a girl he met in the coffee shop. Let the bands stir your own imagination while you stand around the gray gravel lot. Outputmessage performs with Paperhaus and The Effects at 7 p.m. at the Lot at Atlantic Plumbing, 945 Florida Ave. NW. Free. unionkitchendc.com.
