“Let Go,” the new single from The Birdhorse, was written, produced, performed and recorded entirely by Hartley. The new track explodes with serious musical maturation. It was written on a solo trip in the fire of Big Bend National Park on the heels of learning that her longtime partner was pregnant - “a path you have to take.” Elegantly mixed by Ari Picker from Lost in the Trees, “Let Go” is a plea, a spell, an order, a hope, a path forward.
