Gregg Xenakes has 1 Ulali concert.

Ulali was an a capella trio originally composed of Soni, an Apache, Mayan and Yaqui; Pura Fé, and Jennifer (both Tuscaroran). They make simple beats and rhythms more complex with their alluring voices when they sing, shriek and shrill melodically to their music. While some of their songs are sung in English, majority are in different indigenous languages of the Americas.
