Folklore refers to a body of popular music created in Argentina outside the urban center of Buenos Aires. Based on indigenous dance rhythms like the zamba, cueca, chacarera, carnavalito and vidala, these songs were passed on through oral tradition and were virtually unknown outside their own region until the early 20th century. They then became a part of Argentina's regional and national identity. Tierradentro explores this rich trove of music, adding their own colors and textures and expanding the forms of these songs while retaining their rhythmic essence and powerful poetry.
