This new issue of CROLAR – Critical Reviews on Latin American Research- is dedicated to music in Latin America, its "Sound and Dissonance." From salsa in the Caribbean carnaval in Brazil, or to tango in Argentina, to mention a few examples, music has always been inherent to what it means to be "Latin American," sometimes creating stereotypes that can be very hard to overcome. But what does music really mean to Latin America? How can music express a national identity and at the same time connect us to other realities? These are some of the initial questions when putting together this issue, and the submitted reviews help us further the debate.
