Childish Gambino seems to be on a mission to feature all sorts of talent on his songs, but a TDE member was missing on his most recent mixtape, Royalty. That would be Jay Rock, but a new track from his tour DJ, DJ So Super Jam, is released a new mixtape called Trigger Happy and she let out the song "Sour Faces." The song might be unfinished as it sounds a little unpolished and seems to cut off near the end, but still has a tough vibe. Now it seems Gambino needs to work with Kendrick Lamar and then his TDE features are complete. Stream "Sour Faces" below.
