Julie Dorion was the bassist for seminal East Coast Canunk band Eric's Trip, but when that band broke up she decided to play cute, well-written acoustic solo songs. I saw her on tour earlier this year (she was headlining, but her new band Shotgun & Jaybird opened) and it was a beautiful, intimate show. I recommend seeing her live if you have the chance.
Incidentally, she had a split EP with Okkervil River a while back. I think it's out of print now, but it's on OiNK. Very good songs on both halves.
