Few performers these days take the time to pay tribute to the artists whose work shaped their sensibilities. Fewer still make the effort to track down those artists and include them in a project that calls attention to their greatness. Nanci Griffith, on the other hand, has done it twice. Other Voices, Too (A Trip Back to Bountiful) is the sequel to Other Voices, Other Rooms, Griffith's first such collection, which was a triumph on almost every level. The new album is nearly its equal, featuring performances from more than two dozen guest artists, including luminaries such as Ian Tyson, Guy Clark, Lucinda Williams, Richard Thompson, Jimmie Dale Gilmore, John Prine, Rodney Crowell, and Dave Von Ronk. The effect is not unlike that of an old-fashioned (albeit unusually large) guitar pull, with traded vocals, inspired musicianship, well-selected material, and genuine camaraderie.
