Both background songs are by Explosions in the Sky. The first song is called Home (http://www.youtube.com/watch?v=qwk5F-mJH8g).
I do not own this video, nor am I in any way affiliated with Greyskale Multimedia. All credit goes to them. I originally saw this video in Vimeo, I just wanted to share it with YouTube and have GSK's full permission to do so.
