Béla Fleck & Abigail Washburn
Echo in the Valley (Rounder)
This banjo-wielding husband and wife duo each maintained separate solo careers for many years until the logistical demands of raising a young family led them to pool their talents. Their debut album together won a Grammy in 2016 and the follow-up is every bit as exquisite with its stripped-down but intense exploration of the American folk tradition. A Top of the World in #134.
