NORTHWEST PASSAGE: THE BIRTH OF PORTLAND’S DIY CULTURE

Lovingly assembled by Portland renaissance man extraordinaire Mike Lastra, Northwest Passage will fill most of the remaining potholes in your lexicon of Portland’s music scene of yore. By focusing on the burgeoning DIY scene between the ‘78 and ‘83, Northwest Passage succeeds where other punkumentaries have failed. With awesome footage of tons of bands (Poison Idea, Sadonation, The Wipers, The Neo Boys, Lastra’s own Smegma, and Fred Cole’s The Rats) in the throes of creativity fever, Northwest Passage is as entertaining as it is educational. LANCE CHESS Cinema 21.

Tonight at 7 and 9, Cinema 21 (616 NW 21st), $8.
