I've featured a song by Sarah Jarosz before. This one is "Song Up In Her Head", off her album by the same name. In this performance she is all of 17 years old. And that's some mighty fine bluegrass pickin', she'll get better as she goes along but she's already as competent as probably 3/4ths of the bluegrass pickers out there and she writes her own songs besides, including this one.
