Plaintive folk, anyone? Joan Shelley's plucked tunes aren't innovative, but they breathe new light into old traditions. 'Electric Ursa' brings together her compelling voice, which sounds a little like Lotte Kestner -- and sometimes recalls the lower end of Joni Mitchell's register -- with strikingly fluid guitar collaborations. 'Electric Ursa', her second solo record, was produced by Kevin Ratterman, who's also worked with the pastoral folk clown Andrew Bird. These songs are meandering, but it's evident they've been painstakingly constructed.
