Toward the end of his "Green Lights" video, you see NF with a piece of paper that reads "Perception." Turns out that Perception is the name of the album and it's dropping on October 6, 2017. The cover features NF trapped in a prison cell.
So far that's all that has been revealed about the record. It's feasible to assume the preorder and tracklist will be next to release.
