Hears Grimes team up with Bleachers on fresh tune "Entropy"

Grimes is in the midst of creating the long-awaited follow up to 2012's Visions, after scrapping her first attempt last year. She recently unleashed a demo called "REALiTi" that you can hear/watch here.

The pair have collaborated before, on a track from Antonoff's debut record as Bleachers called "Take It Away". Antonoff, very much a pop heavyweight, last year helped co-write portions of Taylor Swift's 1989.
