Originally written for Rihanna, Grimes\’ latest track \”Go\” was not meant to be sung by the Canadian artist herself. But, as they say, when one door is shut another one opens and with Rihanna\’s rejection of the song came an opportunity for Grimes to step outside of her comfort zone and record \”Go\” with the help of fellow Canadian producer Blood Diamonds. While the track is quite different from the usual Grimes sound, it is nothing short of a summer jam and is sure to infect radios and dance floors across the globe during these next few months. This brand new track is available for free download, which you can get below. Also, for those of you lucky enough to live in the Chicagoland area, Grimes will be performing at Pitchfork Music Festival July 20th so go out and see the Canadian sensation live while you have the chance.
