The Motorcycle Diaries

I don't recognize it, sorry... Is it all one song, though?
It's "Apertura", by Gustavo Santaolalla, who plays all the music of the movie.
Does anyone know what the music is from the VERY START of the trailer??
Before it shifts to the song already listed above.

yeah i also downloaded apertura but it's not the song from the very beginning of the trailer.
you could go here to check out the trailer, they have various formats. it's the song at the very beginning.
