"Ate Up All Their Cake" is detailed on Vernon's digital platform PEOPLE as, "a rough draft of a song Phil and Justin worked on last summer. We want to finish it but havent had time in the same space to do so. We're open to ideas."
The description also reveals that the track includes a sample of "live james taylor 1997 in there."
Taking to Twitter to praise the draft track, Vernon describes Cook as his, "main musical teacher AND my life long brother."
Vernon has been busy collaborating away from Bon Iver as last week Stereogum reported that Vernon and Aaron Dessner of the National were to be returning with a new project, named after their first collaboration track "Big Red Machine", that was first unearthed nearly a decade ago.
