This is shown at the end of the movie Motorcycle Diaries.
I actually heard the soundtrack before I saw the movie, and have only seen the movie a few times. I absolutely adore the soundtrack, and have been listening to it for a few years now. It's such a gorgeous rich sound that is produced, and really compliments the stunning cinematography.
I particularly love this song "De Usuahia a la Quiaca" (please don't ask me what it means), and the photographs over it are so raw and really express a deep and strong sense of humanity in pure form, which I love! And is what I love about the film, its purity and honesty.
Motorcycle Diaries has really got me wanting to see South America. My overseas trip may have to be bigger than initially planned.
But, have a listen to this song and look up a few more songs on the soundtrack if you can, it is most definitely worth the listen.
