Wow, this is pretty, Tarantula Arms, the second album from Portland Oregon duo Jenn Rawling and Basho Parks...Jenn the main songwriter and singer, Basho the accompanist on various strummed and bowed string instruments. Rawling's voice has a wonderful little catch in it, a bit of grit that makes the sweetness sweeter. She apparently wrote these songs while working at a fire tower near Mount Hood. The two of them filmed this very stripped down version of "Dead Leg" in the same location.
Though really I like some of the slower material better. Their previous album, Take the Air, can be streamed in its entirety at bandcamp. Very nice.
