Bluegrass, Celtic, Folk
O'Brien has been called a "song sponge". He mines the American music canon for great material; songs collect and abide in his world as comfortably as family heirlooms. They come from around the world, particularly the American South and Ireland. They morph into new ideas and new songs that update old truths about the human condition. They find expression in O'Brien's clear-as-ice voice on stages, in recording studios and at home with circles of gifted musical friends. O'Brien's relationship with songs embodies the very essence of both the folk tradition and its fusion.
