A nice pickup for the library (or for anyone to buy at the local music store or download from places like Rhapsody, iTunes, etc.) would be Adrienne Young. She and her band, Little Sadie, just released their third album, Room to Grow. Others--The Art of Virtue and Plow to the End of the Row--are equally good. Young has a wonderful voice and delivery that works well with her blend of folk, bluegrass and country.
