Abby Posner Abby has been a working musician in Los Angeles for the past 18 years. She is best known for her ability to play nearly any instrument that she can get her hands on, twisting genres, and pushing the boundaries of folk, roots, electronic, and pop music making her "Genre Fluid." If you have seen Abby perform live, you know she can play a mean lead-blues guitar solo, or throw down a complex Earl Scruggs banjo riff. You also may have spotted her playing drums, mandolin, or bass while using her looping pedal. In addition to her versatility, she puts passion and soul into everything she does.
