If you haven’t heard of the cheerfully named supergroup Mr. Sun, you’ve certainly heard its proponents, four of the finest musicians on the American Roots scene: Renowned fiddler Darol Anger, Professor Emeritus at Berklee College of Music, who has released dozens of influential solo albums over a 50-year career in addition to his work with David Grisman and Mike Marshall, and founded the Turtle Island Quartet, Psychograss, and Republic of Strings; Joe K. Walsh, mandolin virtuoso and vocalist who spent four years with the award-winning bluegrass act the Gibson Brothers before becoming a solo artist, songwriter, and Strings Department Professor at Berklee; all-around guitar genius Grant Gordy, a former member of David Grisman’s band and respected solo artist and educator; and the phenomenal Scots bassist Aidan O’Donnell, who has backed harpist Maeve Gilchrist and countless modern jazz heroes.

Their appearances in the last few years at Wintergrass, Rockygrass, Grey Fox, Freshgrass, Redwing Roots, and at IBMA conventions have created a reverberant clang throughout the Acoustic Americana music world.
