I don’t know a lot about Sarah Jarosz, but her website is here. She’s pretty young (born in 1991), but she seems to be making a name for herself. This video is taken from the ‘Transatlantic Sessions’ that bring folk and bluegrass musician together from Ireland and the USA. I don’t recognize everyone in this video, but I know that’s Jerry Douglas on the dobro, and Donal Lunny (formerly of Planxty) is the left-handed bouzouki player. Enjoy!
