How out of the ordinary!! The strange "fragment-like" progression is awesome and makes for some original images in my head (like one of those artistic videos where something that makes no sense in the beginning slowly builds to a full, deep story).
I loved the that rain-stick-like sound giving the rythm and those shy piano notes that would appear. The strings give the song the depth it deserves. Bravo.
I knew that by adding more layers your stuff would become even more amazing. Keep going towards this direction Sam. One of the best songs I've heard from you so far.
