Double your Jeffrey, double your folk tonight at the venerable Doug Fir Lounge. Opening is Jeffrey Martin, local troubadour extraordinaire who’s one of the best anywhere at turning an acoustic guitar and a sad story into a disarmingly gorgeous song. Track down 2014’s Dogs in the Daylight if you’d like to hear one of the very best albums to come out of Portland in recent years. Headlining is Jeffrey Foucault, a roots-music powerhouse originally from Wisconsin but now based out of New England. For years, Foucault has been cranking out well-crafted albums of dusky folk, desolate blues, and twangy rock ’n’ roll, anchored by his old-growth voice and gift for lyrics that explore the human condition in a highly relatable way. Fans of eloquent, affecting songs performed artfully: Bundle up and make the trip to the Doug Fir tonight. You’ll be glad you did, I bet. BEN SALMON
