Book excerpt: Between Norteño and Tejano Conjunto analyzes the origin, evolution, and dissemination of the norteño and tejano conjunto. This group represents a marginalized local identity that was transformed primarily into an identity of the northeast. It then gave way to the whole of northern México and the American Southwest, and was later assimilated internationally as a mainstream genre. This book provides a long-term historic vision of conjunto and the various musical forms it uses, such as polka, corrido, or canción (song), and, more recently, bolero and cumbia, as well as its transformations and contributions to other musical cultures.
