"Fleck's mastery of space and timing puts him outside the canon of most string pluckers, even when what he's doing sounds vaguely traditional. Echo In the Valley is his second release with wife Abigail Washburn following the duo's Grammy-winning eponymous debut in 2016 ... Fleck and Washburn's picking has as much in common with China as Appalachia, and Washburn's yodeling could be home in either region as well. But you have to be careful interpreting the duo's work. The framework often is at odds with the message, in a good way, presented in such a way that you can't allow yourself to get carried away by the melody or lack thereof, needing to concentrate on the lyrics instead".
