NAOMI PUNK, OLIVIA NEUTRON-JOHN, FF, HUGE ROCK

Olympia trio Naomi Punk's aggressively woozy garage rock is suspiciously palatable for the lo-fi-averse, maybe even perfecting the "swamp grunge" non-genre with their distinctly slowed-down, hyper-sludged riffs. Phoenix duo Olivia Neutron-John's no-wave-y, sax-infested synthmares are delivered with a serious bedroom-pop smirk, while local electronic acts the Numbs (Jeff Johnson) and Secret Colors (Matt Lawson) should also incite experimental delight with their collaborative project Huge Rock. Heartland, 8 pm.

EXPO 91

EXPO—Capitol Hill's multipurpose art space Cairo's four-day freakfest of fun—is now in its sixth year, curated with willful weirdness to include some of the best Northwest bands and artists. Go to all the shows if you can, but if you (or your clone) can't make every set, here are some unmissables:

FRIDAY: Nice & AO. Together, Seattle hiphop producers DJAO and Nice Nate construct a fully chopped-and-screwed, nearly subliminally funky brand of slow-head- nodding, future-feet-shuffling, post–FlyLo/Dilla beat science to get subtly down to.

Black Hat. Primitive IDM ambience to elevate your senses to a pleasantly disorienting postindustrial plane.

Also tonight: Electronic-pop act Youryoungbody, addled beats from Newaxeyes, and crafty IDM duo USF.

SATURDAY: Health Problems. Vocalist Ian Kurtis Crist contorts, howls, and generally reanimates Iggy in his prime fronting this noise punk trio. Also worth checking: his synthier, '80s-obsessed projects Bat and Uneven Eyeliner.

Weed. This Vancouver, BC, band released one of 2013's best Northwest albums, Deserve. Walking the sludgy, Dinosaur Jr.–indebted line between emo and 'gazey indie rock, Weed's fuzz-swirl is massively refreshing in a humdrum tornado of dull contemporaries.

Also tonight: Everyone's favorite nap connoisseurs Wimps, garage "supergroup" Childbirth, saxy no-wavers Stickers, and Portland indie rockers Hornet Leg.

SUNDAY: Dragging an Ox Through Water. Portland's Brian Mumford writes bucolic, old-timey country songs skewed with an industrial/noise twist, kind of like being serenaded by an attic full of broken circus memorabilia.

Also tonight: Stranger Genius Award–winning cellist Lori Goldston with Dan Sasaki, Maryjane Dunphe of Olympia punk band Vexx, Corey J. Brewer (Cold Lake, Triumph of Lethargy Skinned Alive to Death), and punk feminist poet Elissa Ball.

Cairo, various times, $7 per day.
