Native American music may not conjure images of tubas, trumpets and John Phillip Sousa marches. Yet this vibrant musical tradition has been a part of Native American culture for more than 100 years. SOUSA ON THE REZ: MARCHING TO THE BEAT OF A DIFFERENT DRUM traces the origins of the four remaining multi-generational, community-based tribal bands: the Iroquois Indian Band from upstate New York, the Fort Mojave Tribal Band from Needles, Calif., the Zuni Pueblo Band from northwestern New Mexico and the Navajo Nation Band from Arizona. Combining profiles of contemporary bands with fresh historical research, SOUSA ON THE REZ offers an unexpected and engaging picture of this little-known aspect of the Native music scene.
