Like the Prodigy-featured "Body" before it, "Sour Face" is another track that didn't quite make the cut for Childish Gambino's Royalty mixtape. Why it didn't isn't particularly clear, especially because Gambino sounds right at home spitting fiery bars alongside Jay Rock. It's interesting to see that the rapper/comedian has worked with three fourths of Black Hippy up to this point--ScHoolboy Q and Ab-Soul appear on Royalty. A Kendrick Lamar collaboration must be on the way, right?
