Zero 7 - The Space Between (also called Space Falls)
I absolutely love this song.
I love the harmony used in this song ... just incredibly moving to me. It's a shame that the harmony mic level is a bit low in this live version until it gets fixed by the second chorus.
There is another video on YouTube of the album version the song that serves as the backdrop for a Kingdom Hearts montage.
I really should go see them live if they ever come around Austin again.
