Before setting to work on her 4th album “I Am Both”, the New York-based singer/songwriter Margaret Glaspy assembled a selection of songs that span from fictional vignettes to unguarded self-revelation to empathetic observation of the troubled world around her. Produced by three-time Grammy winner Joe Henry (Aimee Mann, Joan Baez) at New York City’s Reservoir Studios, “I Am Both” brings Glaspy’s disarmingly direct vocals and eloquent guitar work to a cathartic form of folk-leaning indie-rock.
