Somehow a demo has appeared of the Grimes song 'Go', on the SoundCloud account of Mr Spontaneous, whoever that is. Here is what Grimes posted on tumblr after finding out.

"haha james just sent me this weird demo of go, considering the wackiness of the breakdown i assume this is the orig demo cuz we were extremely caffeinated that day

in any case i dunno if its particularly different from the ‘final version’ but im always interested in hearing demo versions of things so i figured yall mite b. i think we mighta mixed a bit of the soul out of it in retrospect, i appreciate the absurdity of mike’s 2nd drop, the thicker snares in the intro etc. its a bit more crowded

also these are demo vocals for songwriting purposes only and they suck a lot so dont mind them.

** also have no idea how this leaked but it doesn’t seem to hurt anything that it exists."

Hmm, ok, I see. Well, one thing is that the vocals don't "suck a lot" but whatever. Listen to the track below.
