Grimes first teamed up with Bleacher (Fun.’s Jack Antonoff) back in 2014, creating a track entitled “Take Me Away”. Now, the duo are back, coming together to produce the sparkling “Entropy”, which features on HBO’s latest season of Girls. This past week has also seen Grimes sharing a brand new video with us, for “REALiTi“, a demo dating back to 2013. “Entropy” is a dazzling, dreamy pop song, a perfect combination of Grime’s unique, ethereal tones and the slick, shimmering production of Antonoff. Listen to the sweet collaboration below.
