Singer, songwriter, and multi-instrumentalist Olivia Chaney makes her album debut with The Longest River, available April 28 on Nonesuch Records. On the album, Chaney balances her original compositions with a selection of covers she has newly arranged that illustrate the broad sweep of her taste, from jazz to Purcell to folk. "Her voice holds the purity, tension, dignity and sorrow of a heritage full of songs about lost love and cruel fate," says the New York Times. "Ms. Chaney is thoroughly grounded in the past, from medieval music to [Joni] Mitchell. But in her quiet way, she’s radical." The Longest River is available to pre-order with an instant download of the album tracks "Imperfections" and "The King's Horses."
