"Regreso" in Spanish can be both verb in present first person or noun, something like: "I get back, I return" or "The return" . This song is a beautiful chilean huayno and was performed yesterday as a first song by a colombian duet of charango & guitar during the festival "Sonamos Latinoamérica". They made such an atmosphere that there was a gap between the interpretation and the applausses, really magic! Enjoy!!!!!!!!
(I found the original versión with andean winds included at the end of the song, when the festival videos are already at hand, I´ll posted them too!)
