It’s one thing to fall in love with old-time music and learn how to shred on clawhammer-style Appalachian banjo. It’s another to consciously live the life: hitchhiking and riding the rails while learning your craft and writing about your travels. The title track and first single from Meredith Moon’s new album, Constellations, was written in 2017 about the wanderlust of her younger days — not that those days are done. Though she’s not hitchhiking anymore.
