Summary: On Sarah Jarosz's fourth album, Undercurrent, the impact of being a full-time artist living in New York City is palpable. A gifted instrumentalist, singularly expressive vocalist and songwriter of rare insight, Jarosz anchors her new record with a haunting quartet of songs written and performed solo 'Early Morning Light,' 'Everything to Hide,' 'Take Another Turn' and 'Jacqueline.' She expands her palate from the swampy defiance of 'House of Mercy' to the nostalgic 'Back of My Mind.' Undercurrent captures the process of personal evolution and discovery as well as the inspirational nature of change.
