For the past decade, the Northwest music scene has been blessed by Three Imaginary Girls, whose website indefatigably celebrates the “sparkly indie-pop” world. Tonight, TIG celebrates its 10th anniversary with some of the sparkliest indie-pop purveyors at work today: London’s Allo Darlin’, led by escaped Australian Elizabeth Morris, who plays ukulele, writes songs about diagnosing relationships via Woody Allen’s cinematic archetypes and making chili, and is brilliant. Sharing the bill: London art-poppers the Wave Pictures. (Vera Project, 305 Harrison St, www.theveraproject.org, 7:30 pm, $11, all ages)
