The story goes deep with this one...
I love the music. The instruments - is that a pan flute too? Though unfortunately the song - though tonally just perfect - is a little hard to understand, and seems to be heavily processed too, not sure if it's autotone or something else to intentionally give it this airy effect. It contributes to the atmosphere, though I find it also sounds a little artificial, and either due to effects or accent (or a combination thereof) it's not so easy to catch the lyrics... which by the way are beautiful!
I love the atmosphere, and the story behind it. With that in mind I couldn't possibly suggest someone else sing this, but I do feel the vocals are unfortunately the weak point. Read that you removed the vocoder but I still find it hard to make out the words, the delivery's a little mechanic sometimes; the accent's there; there's a lot of reverb and layers of wonderful sound the flow over the song...
So good but a little hard to hear; a little restrained vocally...
