This is beat-driven world fusion with a focus on Native American tradional music. Though the liner notes of the first Spirit Nation album led me to believe that vocalist Judy Crescenzo was the impetus behind the project, an hour of scouring the web eventually revealed that this project is really Waterbone by another name. Well, that's not quite right either - Jimmy Waldo (producer, synthesist) and David Evans (executive producer, guitarist) created Spirit Nation without Waterbone's D. Kendall Jones. In any case, the second Spirit Nation album features a completely different vocalist, so my initial impression was obviously wrong. This is the best bio I've been able to find.
