Fiona Ritchie has explored the world of Celtic music on her long-running NPR program, The Thistle & Shamrock; Doug Orr is the president emeritus of Warren Wilson College, where he founded the Swannanoa Gathering music workshops. Working together, the two have produced a bountiful project, Wayfaring Strangers: The Musical Voyage from Scotland and Ulster to Appalachia (North Carolina, $39.95). The story of Appalachian music and its origins is the story of two migrations; the Scots first went to Ulster, and then to America. These pages contain treasures. Filled with photos, prints, maps, interviews—with singers, players, scholars, and song collectors—and fascinating sidebars on topics ranging from ballad types, fiddle styles, and the ceili to the Great Philadelphia Wagon Road, Cape Breton, African American string bands, and “homesick pioneers.” Best of all, the book comes with a CD of twenty songs, all expertly selected and arranged, featuring some of the musicians profiled in this volume. A glossary, timeline, bibliography, discography, and list of resource centers will lead the curious to yet more treasures.
