Indeed - that Sarah Jorosz CD is great. It came out in 2009 though. A bit more recent if you like her...perhaps...folksy, alt-country, girl with beautiful voice and string instruments...one of my favorites of recent is Martha Tilston, Lucy and the Wolves, and Emily Barker, Despite the Snow (ok that one is 2008, but it's just stunning). Also great - and actually released in 2011; Bobby Long, A Winter's Tale. More girls with banjos and amazing vocals - The Wailin' Jennys (any of their albums are great and they do have a new one just out - I like the live one at Mauch Opera House, which you can get in high rez at HD Tracks).
