If you could take a shiver and slow it down so that it lasted for 50 minutes, you'd have Red Planet, the fourth album from Arborea. It's folk music that runs through your veins ice cold, but in a way that's so compelling and irresistible you can't help be moved by it. Red Planet is released by Portland label Strange Attractors Audio House, but Arborea actually hail from a spot much closer to the other Portland; the husband-and-wife duo of Shanti and Buck Curran live in Maine, a state of rugged beauty, endless forests, summertime bugs the size of hummingbirds, and a cold and rocky coastline. Shanti's voice rises above sparse instrumental backing like a cool fog, and while the pair has earned comparisons to acts like Pentangle and Alela Diane (whose sometime backup singer Alina Hardin opens tonight's show), to me Arborea sounds utterly unique and entirely captivating.
