Polyon describes itself as “fuzz rock” influenced by “toxic space debris”—which, according to my sub-genre-to-English decoder, means a lot of early-aughts gloom rock. So far, so Fort Reno. You’re braving mosquitoes and wet blankets here for Jack on Fire, a band-cum-prankster collective that sounds like Le Tigre in the last days of the Weimar Republic. Jack on Fire hit the big time last year with a song urging listeners to burn down the Brixton, the most prominent house on U Street’s Greek Row. Since then, the group has made posters accusing Mayor Muriel Bowser of being a sleeper agent for the condo agenda and cultivated feuds with members of Congress. In Jack on Fire’s telling, pot-hating Rep. Andy Harris just needs to smoke up, and pro-life Rep. Trent Franks should’ve been aborted. I suspect Jack on Fire is more at home in the new D.C. than its members realize, though—“Slam Piece,” their plaintive song about the kind of friends-with-benefits pitch that might go down over IPAs at the Brixton, is downright romantic. Jack on Fire performs with Polyon at 7 p.m. at Fort Reno, Nebraska Avenue and Chesapeake Street NW. Free. fortreno.com.
