One of the most prolific country folk songwriters alive today, and she's still relatively unknown which is amazing. You may recognize her voice from her contribution to the O Brother, Where Art Thou? soundtrack. This thursday at The Troubadour in Los Angeles she will be accompanying her longtime songwriter and harmonizer Dave Rawlings and his first ever headlining slot as a front man as The Dave Rawlings Machine. Rawlings alone is a tremendous songwriter who has helped boost notable acts such as Old Crow Medicine Show and Ryan Adams to fame, but when he and Gillian perform together, magic happens. Just watch the video.
