He has put his indelible stamp on thirteen songs, most of which are either traditional or have been composed in that style by writers with deep connections to what is now called “American Roots Music.” Happy is accompanied by a cast of A-list musicians and singers, most of whom have been playing with him on and off for years. They include multi-instrumentalist Larry Campbell; harp player John Sebastian; bassist Byron Isaacs; drummer Eric Parker; slide guitarist Cindy Cashdollar, vocalists Geoff Muldaur, Amy Helm, Zach Djanikian and Eugene Ruffolo; banjo wiz Tony Trischka, fiddle virtuoso Darol Anger, and Happy’s son, guitarist Adam Traum, among others.
