Sarah Jarosz just released 'World on the Ground,' her first solo album in four years. On this week's Fretboard Journal Podcast, she talks to us about the making of the album, working with John Leventhal (who produced the project and helped co-write a few songs), her favorite songwriting tools (including her Collings D1A and her Fletcher Brock-built octave mandolin), and much more.
