In The Tango Machine, ethnomusicologist Morgan Luker examines the new and different ways contemporary tango music has been drawn upon and used as a resource for cultural, social, and economic development in Buenos Aires, Argentina. In doing so, he addresses broader concerns about how the value and meaning of musical culture has been profoundly reframed in the age of expediency where music and the arts are called upon and often compelled to address social, political and economic problems that were previously located outside the cultural domain. Long hailed as Argentina s so-called national genre of popular music and dance, tango has not been musically or socially popular in Argentina since the late 1950s, and today the vast majority of Argentines consider tango to be little more than a kitschy remnant of an increasingly distant past. Nevertheless, tango continues to have salience as a potent symbol of Argentine culture within the national imaginary and global representations. Ultimately, Luker argues that tango in Buenos Aires is not exceptional, but in fact emblematic of musical culture in the age of expediency, where the value and meaning of music and the arts are largely defined by their usability within broader social, political, and economic projects. Luker tackles here some of the core conceptual challenges facing critical music scholarship; the book will be an important resource for readers in ethnomusicology and music, anthropology, cultural studies, and Latin American studies."
