There are strong connections between the modern songs of large cities and the ancestral music rooted in the depths of Latin America. Taking as a starting point the recordings made by the collector and musicologist Leda Valladares and her subsequent connection with rock musicians in the 80s and 90s, we will embark on a journey of sonic discovery, in search of meeting points between the singing from the valleys and mountains of Argentina and the Rock and Blues born in one of the continent's rock capitals, Buenos Aires.
