An NPR Music YouTube video of Sierra Hull’s recent Tiny Desk Concert boasts countless effusive comments, ranging from "American treasure" to "absolute ripper" and "best in the world." The six-time International Bluegrass Music Association Mandolin Player of the Year and two-time Grammy nominee lives up to those accolades at two regional performances with troubadour extraordinaire John Craigie, at New Hampshire’s Lebanon Opera House and Spruce Peak Performing Arts Center in Stowe. The acoustic masters promise next-level Americana and bluegrass music, accented by picking prowess, heartfelt storytelling and boundary-pushing innovation.
