This comprehensive survey examines Latin American music, focusing on popular-as opposed to folk or art-music and containing more than 200 entries on the concepts and terminology, ensembles, and instruments that the genre comprises. The rich and soulful character of Latin American culture is expressed most vividly in the sounds and expressions of its musical heritage. While other scholars have attempted to define and interpret this body of work, no other resource has provided such a detailed view of the topic, covering everything from the mambo and unique music instruments to the biographies of famous Latino musicians. Encyclopedia of Latin American Popular Music delivers scholarly, authoritative, and accessible information on the subject, and is the only single-volume reference in English that is devoted to an encyclopedic study of the popular music in this genre.
