Claire Boucher returns with a new song.

Grimes has shared ‘Go’, a collaboration with friend and OWSLA signee Blood Diamonds. As widely reported, the song was originally written for Rihanna.

“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 writes in a press release (via Pitchfork).

Stream/download ‘Go’ below. We’re happy to hear new material from Grimes, but probably not as happy as she is: “releasing music is like having a baby but probably a lot less gestation and pain,” she tweets.
