Details: 2016 release. Weighted Mind is a landmark achievement, not just in Sierra Hull's career, but in the world of folk-pop, bluegrass, and acoustic music overall. With instrumentation comprised largely of mandolin, bass, and vocals, this is genre-transcending music at it's best, with production by Béla Fleck and special harmony vocal guests Alison Krauss, Abigail Washburn, and Rhiannon Giddens adding to the luster. Béla Fleck special guests on banjo on two tracks and duo partner, Ethan Jodziewicz provides the bass.
