flOw trailer
 

Im not sure if this is the best place to ask, but I recently saw a trailer on youtube for the game flOW.

Here is the trailer in question

However, I am interested to find what music it is playing. Ive looked around the net and It seems to me that the music does not belong to the game originally. Can anyone tell me where the music is from? Or confirm that it does indeed belong to the game.
