Their blend of Celtic-influenced Canadiana, Americana, Newgrass and beyond combusts in a sparking gap of three adept musicians who produce poignant, versatile and sincere music. Bruce Coughlin is the songwriter and guitarist; Nolan Murray, a mandolin, fiddle and banjo champ. Laurence Knight has toured playing bass with Bo Diddley and others. Tillers Folly preserves and promotes Pacific Northwest history in song. See tillersfolly.com

Sean Gaskell plays the 21 string West African Kora and opens the evening’s festivities. His 300 year old instrument is traditionally played by Griots (Gree-ohs) and the oral musical historians of the Mandinka people. Studying extensively under the instruction of Kora masters, Gaskell has played Kartong Festival in Gambia and Dombondir Festival in Senegal.
