[SOLVED] Which song is in the documentary background

Hi, I'm trying to find the song that is in this documentary http://www.youtube.com/watch?v=T34qIX1wZ08 it starts at 2:37.

Sadly there are no credits in the end of the movie and no one asked in comments.

The XX - Intro http://www.youtube.com/watch?v=sV4_wHvP7b8

Thanks Mixalopoulos!!
