[2] Produced by Peter Asher, the album features musical appearances by bassist Esperanza Spalding, fiddlers Nicky Sanders and Sara Watkins, and guitarist Waddy Wachtel.

Backing vocals and instrumental accompaniment were also performed by all contemporaneous members of the band Steep Canyon Rangers who would tour extensively with Martin and Brickell following the record release.

[3] Altered versions of "When You Get to Asheville" and "Sun's Gonna Shine" later appeared in Martin and Brickell's 2014 musical, Bright Star.

[4] The groundwork for the project arose from casual conversations in which Brickell had complimented Martin on his bluegrass records, and he in turn, offered her a melody he’d composed, but for which he did not have any lyrics.

According to Martin in this early stage the project was without any set goal — "We were being led by the songs, not any kind of deal or agent"[4] as he would later recall.
