These inter-tribal pow-wow songs are by the Grosventre and Assinaboine, with some Chippewa Cree members. Included are dance songs, trick songs, grass dance songs and contest songs in the text-driven updated traditional vein whose main interest for those who don't understand the lyrics is the exhilarating and idiosyncratic choral sound. This, particularly in the case of the Rio Grande singers (as of other pueblo groups I've heard), is powerful in the extreme. The lack of notes is a pity: the apparent underlying assumption -- if you're listening, you already know -- is increasingly less accurate these days.
