Sul lago Tahoe

Does anyone know who sings "La lloroncita", the end credits' song ? I loved it but can't seem to find out who sings it…

Regarding the movie, i was under the charm of its slowness, the drama increasing gradually to an issue that i definitely found worth the while. I enjoyed these long moments of wait with the characters, i loved that tale of minuscule things. What else ?… Lots of humour and weird characters accompany the boy through what can definitely be named a journey of initiation to aspects of life. Lots of emotion and empathy are present here as well.

I heard the director made the movie out of his personal experience. Maybe its truth comes partly from there.
