This sounds a lot like the lonely (but comforting) guitar tracks in The Last of Us, a video game for the PS3 that has won high critical acclaim in practically all of the categories you can think of. If you haven't played it yet, I think you'll appreciate the experience of immersing yourself in a lonely, hostile world with beautiful sound design and visuals. The composer's name is Gustavo Santaolalla, and when you play through this masterpiece, you'll realize where your own soundbite could easily fit in with his music as well. Fantastic work. Thank you for sharing this with us!
