Collide-O-Scope
Historically, the only things Portland’s gotten from Seattle are an invasion of dead-eyed Amazon worker bees and a traffic epidemic. But every once in a while, something actually worthwhile comes from up northโ€”like Collide-O-Scope, a live show that, for almost a decade, has been weirding out Seattle moviegoers with a campily curated mix of โ€œeducational films, B-movie gems, lost Euro-disco classics, news bloopers, and indescribable visual delights.โ€ Tonight, Collide-O-Scope hits the Hollywood Theatre, and your eyes will never be the same.

Wooden Indian Burial Ground, Sacred Trees
The wonderfully garage-y Portland favorites Wooden Indian Burial Ground are a model of consistency. Frontman Justin Fowlerโ€™s manic guitar leads the charge, squirting bizarre squeals in walls of effects. The rhythm section is renowned, too, and bassist Samuel Farrell and drummer Daniel Galucki provide a rock-solid foundation for Fowlerโ€™s unrestrained six-string dalliances. RYAN J. PRADO

Double Indemnity
Billy Wilderโ€™s career is defined by his comedies, including some of the genreโ€™s very best entries, like Some Like it Hot and The Apartment. But Wilder put just as big a stamp on film noir with 1944โ€™s Double Indemnity, a coldly efficient little ice pick of a thriller starring Barbara Stanwyck as the prototypical femme fatale, and Fred MacMurray as one of the best oafish dopes to ever get suckered onscreen, with Edward G. Robinson amiably thieving the movie right out from under both of them. Film noir basically starts here, and Wilder changed the face of cinema in less than two hours. BOBBY ROBERTS
7 pm, NW Film Center’s Whitsell Auditorium

Ural Thomas & the Pain
To live in Portland and never have seen Ural Thomas and the Painโ€”a resurrected local treasure of soul if there ever was oneโ€”would be a shame. MARJORIE SKINNER
