Sister (407 Central NW) welcomes three intriguing bands into its dark, comfortable and acoustically wondrous environs on the evening of Wednesday, July 30. No wave fiesta ensemble The Coathangers headlines the show. The band hails from Atlanta, Ga., and were brought to prominence by their notoriously rocking, succinctly on target and politically incorrect tuneage like “Nestle in My Boobies.” With a live show that invites rollicking audience participation and celebratory glimpses of a fabled punk partyland, The Coathangers—including guitarist Julia Kugel, bassist Meredith Franco and drummer Stephanie Luke—runs the narrative and sonic gamut from early evening glow to next morning disillusion. Before The Coathangers test the boundaries of genre, gender and jumpability, Willamette River shredders White Fang, featuring ever-wild front man Erik Gage, will bring their ultra-noisy cacophony of basement-based DIY punk along for the ride. Primitive in execution but certain in their advocacy of atonal jaunts into the rocanrol wilderness, White Fang are considered one of the prime movers of Portland’s punk scene. With smokingly honest work like “Feeling Shitty” and “Can’t Find my Weed,” White Fang’s songs spin you around violently and leave you out in the tundra for the wolves. Local psych-demons—and arhats of all that is noisily pop-fragranced—Abandoned Mansions opens the evening frolic with a collection of songs guaranteed to melt your brain and get you primed for a dance hall that may later transform into a gleefully sweaty mosh pit. Abandoned Mansions showcases the prodigiously zoomy talents of Burqueños Pablo Novelas, Rene Aguilera and Kris Kerby. This Saturday night, 21-plus rock fest deluxe begins at 9pm, and you can get in for a measly seven bucks. Doors are at 8pm.
