Now in its sixth year, Peter Koslik and Nick Arthur’s Northwest Psych Fest does an excellent job showcasing local and international talent on a small budget. Their connections with the Mexican psych-rock underground again pay dividends with Dorotheo and Los Dug Dugs bringing their transportive, melodious songs to the Sunset. In the 1970s, this Mexican group (LDD) forged a canon ablaze with artfully brutal rock and gritty earworms. Their songs wield a galvanizing power combined with a melodic brilliance that’s rarely heard these days. Other highlights include polyglot avant-rock dynamos Diminished Men and epic outer-limits jammers WEEED. It’s a loaded bill to get loaded to, for sure. by Dave Segal
