Steven Feld is a ethnomusicologist who teaches sound communication at the University of Pennsylvania. Ethnomusicology combines anthropology and music theory, and attempts to learn about culture through music. Feld is also a jazz musician who has incorporated the genre into his work. His work has taken him to Papua New Guinea, where he studied the Kaluli tribe, and the Southwestern United States. He joins the show to discuss his work. (INTERVIEW BY DANNY MILLER.)
