The distinguished scholar Steven Feld shaped the field of the anthropology of sound and music. In this new work, he looks at the vernacular cosmopolitanism of a group of jazz players in Ghana, including some who have traveled widely, played with American jazz greats, and blended Coltrane with local instruments and philosophy. He describes their cosmopolitan outlook as an accoustemology, a way of knowing the world through sound. Feld combines memoir, biography, ethnography, and history, telling a story of diasporic intimacy and dialogue that contests both American nationalist and Afrocentric narrations of jazz history.
