Grimes is back today with her first new track in almost two years called "Go" featuring Blood Diamonds. She premiered it during her live set at Governors Ball earlier this month, and today the official version was played on Zane Lowe's Radio 1 show. She originally wrote the song for Rihanna but it was rejected, which she announced during her Governors Ball performance.

"Go" is streaming below and available for free download on her website. “It’s our summer jam so we figured we should put it out cuz I am very bored of waiting to finish my album b4 releasing new music haha," she said in a statement. Grimes is currently working on the follow-up album to her 2012 release, Visions.
