“Let Go” is the first single from The Birdhorse’s third effort coming in 2020. The Southern Sounding says the track serves up "a ramble of folk intimacy mixed with circuital experiments which clings to your bones and organs." Written, produced, performed and recorded entirely by Hartley, the new track explodes with serious musical maturation. A breathless whisper delivers full-throated and unrestricted. “Let Go” 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 the orchestral folk-pop band Lost in the Trees, “Let Go” is a plea, a spell, an order, a hope, a path forward.
